The AI firm Anthropic has developed a way to peer inside a large language model and watch what it does as it comes up with a response, revealing key new insights into how the technology works. The takeaway: LLMs are even stranger than we thought. The Anthropic team was surprised by some of the counterintuitive workarounds that large language models appear to use to complete sentences, solve simple math problems, suppress hallucinations, and more, says Joshua Batson, a research scientist at the company. Its no secret that large language models work in mysterious ways. Fewif anymass-market technologies have ever been so little understood. That makes figuring out what makes them tick one of the biggest open challenges in science. But its not just about curiosity. Shedding some light on how these models work would expose their weaknesses, revealing why they make stuff up and can be tricked into going off the rails. It would help resolve deep disputes about exactly what these models can and cant do. And it would show how trustworthy (or not) they really are. Batson and his colleagues describe their new work in two reports published today. The first presents Anthropics use of a technique called circuit tracing, which lets researchers track the decision-making processes inside a large language model step by step. Anthropic used circuit tracing to watch its LLM Claude 3.5 Haiku carry out various tasks. The second (titled On the Biology of a Large Language Model) details what the team discovered when it looked at 10 tasks in particular. I think this is really cool work, says Jack Merullo, who studies large language models at Brown University in Providence, Rhode Island, and was not involved in the research. Its a really nice step forward in terms of methods. Circuit tracing is not itself new. Last year Merullo and his colleagues analyzed a specific circuit in a version of OpenAIs GPT-2, an older large language model that OpenAI released in 2019. But Anthropic has now analyzed a number of different circuits as a far larger and far more complex model carries out multiple tasks. Anthropic is very capable at applying scale to a problem, says Merullo. Eden Biran, who studies large language models at Tel Aviv University, agrees. Finding circuits in a large state-of-the-art model such as Claude is a nontrivial engineering feat, he says. And it shows that circuits scale up and might be a good way forward for interpreting language models. Circuits chain together different partsor componentsof a model. Last year, Anthropic identified certain components inside Claude that correspond to real-world concepts. Some were specific, such as Michael Jordan or greenness; others were more vague, such as conflict between individuals. One component appeared to represent the Golden Gate Bridge. Anthropic researchers found that if they turned up the dial on this component, Claude could be made to self-identify not as a large language model but as the physical bridge itself. The latest work builds on that research and the work of others, including Google DeepMind, to reveal some of the connections between individual components. Chains of components are the pathways between the words put into Claude and the words that come out. Its tip-of-the-iceberg stuff. Maybe were looking at a few percent of whats going on, says Batson. But thats already enough to see incredible structure. Growing LLMs Researchers at Anthropic and elsewhere are studying large language models as if they were natural phenomena rather than human-built software. Thats because the models are trained, not programmed. They almost grow organically, says Batson. They start out totally random. Then you train them on all this data and they go from producing gibberish to being able to speak different languages and write software and fold proteins. There are insane things that these models learn to do, but we dont know how that happened because we didnt go in there and set the knobs. Sure, its all math. But its not math that we can follow. Open up a large language model and all you will see is billions of numbersthe parameters, says Batson. Its not illuminating. Anthropic says it was inspired by brain-scan techniques used in neuroscience to build what the firm describes as a kind of microscope that can be pointed at different parts of a model while it runs. The technique highlights components that are active at different times. Researchers can then zoom in on different components and record when they are and are not active. Take the component that corresponds to the Golden Gate Bridge. It turns on when Claude is shown text that names or describes the bridge or even text related to the bridge, such as San Francisco or Alcatraz. Its off otherwise. Yet another component might correspond to the idea of smallness: We look through tens of millions of texts and see its on for the word small, its on for the word tiny, its on for the word petite, its on for words related to smallness, things that are itty-bitty, like thimblesyou know, just small stuff, says Batson. Having identified individual components, Anthropic then follows the trail inside the model as different components get chained together. The researchers start at the end, with the component or components that led to the final response Claude gives to a query. Batson and his team then trace that chain backwards. Odd behavior So: What did they find? Anthropic looked at 10 different behaviors in Claude. One involved the use of different languages. Does Claude have a part that speaks French and another part that speaks Chinese, and so on? The team found that Claude used components independent of any language to answer a question or solve a problem and then picked a specific language when it replied. Ask it What is the opposite of small? in English, French, and Chinese and Claude will first use the language-neutral components related to smallness and opposites Anthropic also looked at how Claude solved simple math problems. The team found that the model seems to have developed its own internal strategies that are unlike those it will have seen in its training data. Ask Claude to add 36 and 59 and the model will go through a series of odd steps, including first adding a selection of approximate values (add 40ish and 60ish, add 57ish and 36ish). Towards the end of its process, it comes up with the value 92ish. Meanwhile, another sequence of steps focuses on the last digits, 6 and 9, and determines that the answer must end in a 5. Putting that together with 92ish gives the correct answer of 95. And yet if you then ask Claude how it worked that out, it will say something like: I added the ones (6+9=15), carried the 1, then added the 10s (3+5+1=9), resulting in 95. In other words, it gives you a common approach found everywhere online rather than what it actually did. Yep! LLMs are weird. (And not to be trusted.) The steps that Claude 3.5 Haiku used to solve a simple math problem were not what Anthropic expectedthey're not the steps Claude claimed it took either. ANTHROPIC This is clear evidence that large language models will give reasons for what they do that do not necessarily reflect what they actually did. But this is true for people too, says Batson: You ask somebody, Why did you do that? And theyre like, Um, I guess its because I was . You know, maybe not. Maybe they were just hungry and thats why they did it. Biran thinks this finding is especially interesting. Many researchers study the behavior of large language models by asking them to explain their actions. But that might be a risky approach, he says: As models continue getting stronger, they must be equipped with better guardrails. I believeand this work also showsthat relying only on model outputs is not enough. A third task that Anthropic studied was writing poems. The researchers wanted to know if the model really did just wing it, predicting one word at a time. Instead they found that Claude somehow looked ahead, picking the word at the end of the next line several words in advance. For example, when Claude was given the prompt A rhyming couplet: He saw a carrot and had to grab it, the model responded, His hunger was like a starving rabbit. But using their microscope, they saw that Claude had already hit upon the word rabbit when it was processing grab it. It then seemed to write the next line with that ending already in place. This might sound like a tiny detail. But it goes against the common assumption that large language models always work by picking one word at a time in sequence. The planning thing in poems blew me away, says Batson. Instead of at the very last minute trying to make the rhyme make sense, it knows where its going. I thought that was cool, says Merullo. One of the joys of working in the field is moments like that. Theres been maybe small bits of evidence pointing toward the ability of models to plan ahead, but its been a big open question to what extent they do. Anthropic then confirmed its observation by turning off the placeholder component for rabbitness. Claude responded with His hunger was a powerful habit. And when the team replaced rabbitness with greenness, Anthropic also explored why Claude sometimes made stuff up, a phenomenon known as hallucination. Hallucination is the most natural thing in the world for these models, given how theyre just trained to give possible completions, says Batson. The real question is, How in Gods name could you ever make it not do that? The latest generation of large language models, like Claude 3.5 and Gemini and GPT-4o, hallucinate far less than previous versions, thanks to extensive post-training (the steps that take an LLM trained on the internet and turn it into a usable chatbot). But Batsons team was surprised to find that this post-training seems to have made Claude refuse to speculate as a default behavior. When it did respond with false information, it was because some other component had overridden the dont speculate component. This seemed to happen most often when the speculation involved a celebrity or other well-known entity. Its as if the amount of information available pushed the speculation through, despite the default setting. When Anthropic overrode the dont speculate component to test this, Claude produced lots of false statements about individuals, including claiming that Batson was famous for inventing the Batson principle (he isnt). Still unclear Because we know so little about large language models, any new insight is a big step forward. A deep understanding of how these models work under the hood would allow us to design and train models that are much better and stronger, says Biran. But Batson notes there are still serious limitations. Its a misconception that weve found all the components of the model or, like, a Gods-eye view, he says. Some things are in focus, but other things are still uncleara distortion of the microscope. And it takes several hours for a human researcher to trace the responses to even very short prompts. Whats more, these models can do a remarkable number of different things, and Anthropic has so far looked at only 10 of them. Batson also says there are big questions that this approach wont answer. Circuit tracing can be used to peer at the structures inside a large language model, but it wont tell you how or why those structures formed during training. Thats a profound question that we dont address at all in this work, he says. But Batson sees this as the start of a new era in which it is possible, at last, to find real evidence for how these models work: We dont have to be, like: Are they thinking? Are they reasoning? Are they dreaming? Are they memorizing? Those are all analogies. But if we can literally see step by step what a model is doing, maybe now we dont need analogies.

MIT Technology Review Explains: Let our writers untangle the complex, messy world of technology to help you understand whats coming next. You can read more from the series here. With the recent news that the Atlantics editor in chief was accidentally added to a group Signal chat for American leaders planning a bombing in Yemen, many people are wondering: What is Signal? Is it secure? If government officials arent supposed to use it for military planning, does that mean I shouldnt use it either? The answer is: Yes, you should use Signal, but government officials having top-secret conversations shouldnt use Signal. Read on to find out why. What is Signal? Signal is an app you can install on your iPhone or Android phone, or on your computer. It lets you send secure texts, images, and phone or video chats with other people or groups of people, just like iMessage, Google Messages, WhatsApp, and other chat apps. Installing Signal is a two-minute processagain, its designed to work just like other popular texting apps. Why is it a problem for government officials to use Signal? Signal is very secureas well see below, its the best option out there for having private conversations with your friends on your cell phone. But you shouldnt use it if you have a legal obligation to preserve your messages, such as while doing government business, because Signal prioritizes privacy over ability to preserve data. Its designed to securely delete data when youre done with it, not to keep it. This makes it uniquely unsuited for following public record laws. You also shouldnt use it if your phone might be a target of sophisticated hackers, because Signal can only do its job if the phone it is running on is secure. If your phone has been hacked, then the hacker can read your messages regardless of what software you are running. This is why you shouldnt use Signal to discuss classified material or military plans. For military communication your civilian phone is always considered hacked by adversaries, so you should instead use communication equipment that is saferequipment that is physically guarded and designed to do only one job, making it harder to hack. What about everyone else? Signal is designed from bottom to top as a very private space for conversation. Cryptographers are very sure that as long as your phone is otherwise secure, no one can read your messages. Why should you want that? Because private spaces for conversation are very important. In the US, the First Amendment recognizes, in the right to freedom of assembly, that we all need private conversations among our own selected groups in order to function. And you dont need the First Amendment to tell you that. You know, just like everyone else, that you can have important conversations in your living room, bedroom, church coffee hour, or meeting hall that you could never have on a public stage. Signal gives us the digital equivalent of thatits a space where we can talk, among groups of our choice, about the private things that matter to us, free of corporate or government surveillance. Our mental health and social functioning require that. So if youre not legally required to record your conversations, and not planning secret military operations, go ahead and use Signalyou deserve the privacy. How do we know Signal is secure? People often give up on finding digital privacy and end up censoring themselves out of caution. So are there really private ways to talk on our phones, or should we just assume that everything is being read anyway? The good news is: For most of us who arent individually targeted by hackers, we really can still have private conversations. Signal is designed to ensure that if you know your phone and the phones of other people in your group havent been hacked (more on that later), you dont have to trust anything else. It uses many techniques from the cryptography community to make that possible. Most important and well-known is end-to-end encryption, which means that messages can be read only on the devices involved in the conversation and not by servers passing the messages back and forth. But Signal uses other techniques to keep your messages private and safe as well. For example, it goes to great lengths to make it hard for the Signal server itself to know who else you are talking to (a feature known as sealed sender), or for an attacker who records traffic between phones to later decrypt the traffic by seizing one of the phones (perfect forward secrecy). These are only a few of many security properties built into the protocol, which is well enough designed and vetted for other messaging apps, such as WhatsApp and Google Messages, to use the same one. Signal is also designed so we dont have to trust the people who make it. The source code for the app is available online and, because of its popularity as a security tool, is frequently audited by experts. And even though its security does not rely on our trust in the publisher,it does come from a respected source: the Signal Technology Foundation, a nonprofit whose mission is to protect free expression and enable secure global communication through open-source privacy technology. The app itself, and the foundation, grew out of a community of prominent privacy advocates. The foundation was started by Moxie Marlinspike, a cryptographer and longtime advocate of secure private communication, and Brian Acton, a cofounder of WhatsApp. Why do people use Signal over other text apps? Are other ones secure? Many apps offer end-to-end encryption, and its not a bad idea to use them for a measure of privacy. But Signal is a gold standard for private communication because it is secure by default: Unless you add someone you didnt mean to, its very hard for a chat to accidentally become less secure than you intended. Thats not necessarily the case for other apps. For example, iMessage conversations are sometimes end-to-end encrypted, but only if your chat has blue bubbles, and they arent encrypted in iCloud backups by default. Google Messages are sometimes end-to-end encrypted, but only if the chat shows a lock icon. WhatsApp is end-to-end encrypted but logs your activity, including how you interact with others using our Services. Signal is careful not to record who you are talking with, to offer ways to reliably delete messages, and to keep messages secure even in online phone backups. This focus demonstrates the benefits of an app coming from a nonprofit focused on privacy rather than a company that sees security as a nice to have feature alongside other goals. (Conversely, and as a warning, using Signal makes it rather easier to accidentally lose messages! Again, it is not a good choice if you are legally required to record your communication.) Applications like WhatsApp, iMessage, and Google Messages do offer end-to-end encryption and can offer much better security than nothing. The worst option of all is regular SMS text messages (green bubbles on iOS)those are sent unencrypted and are likely collected by mass government surveillance. Wait, how do I know that my phone is secure? Signal is an excellent choice for privacy if you know that the phones of everyone youre talking with are secure. But how do you know that? Its easy to give up on a feeling of privacy if you never feel good about trusting your phone anyway. One good place to start for most of us is simply to make sure your phone is up to date. Governments often do have ways of hacking phones, but hacking up-to-date phones is expensive and risky and reserved for high-value targets. For most people, simply having your software up to date will remove you from a category that hackers target. If youre a potential target of sophisticated hacking, then dont stop there. Youll need extra security measures, andguides from the Freedom of the Press Foundation and the Electronic Frontier Foundation are a good place to start. But you dont have to be a high-value target to value privacy. The rest of us can do our part to re-create that private living room, bedroom, church, or meeting hall simply by using an up-to-date phone with an app that respects our privacy.

But so far, he has little to show for the effort. Skelly has long argued that building such lines and linking together the nations grids would accelerate the shift from coal- and natural-gas-fueled power plants to the renewables needed to cut the pollution driving climate change. But his previous business shut down in 2019, after halting two of its projects and selling off interests in three more.

Glaciers generally move so slowly you cant see their progress with the naked eye. (Their pace is glacial.) But these massive bodies of ice do march downhill, with potentially planet-altering consequences. Theres a lot we dont understand about how glaciers move and how soon some of the most significant ones could collapse into the sea. That could be a problem, since melting glaciers could lead to multiple feet of sea-level rise this century, potentially displacing millions of people who live and work along the coasts. A new group is aiming not only to further our understanding of glaciers but also to look into options to save them if things move toward a worst-case scenario, as my colleague James Temple outlined in his latest story. One idea: refreezing glaciers in place. The whole thing can sound like science fiction. But once you consider how huge the stakes are, I think it gets easier to understand why some scientists say we should at least be exploring these radical interventions. Its hard to feel very optimistic about glaciers these days. (The Thwaites Glacier in West Antarctica is often called the doomsday glaciernot alarming at all!) Take two studies published just in the last month, for example. The British Antarctic Survey released the most detailed map to date of Antarcticas bedrockthe foundation under the continents ice. With twice as many data points as before, the study revealed that more ice than we thought is resting on bedrock thats already below sea level. That means seawater can flow in and help melt ice faster, so Antarcticas ice is more vulnerable than previously estimated. Another study examined subglacial riversstreams that flow under the ice, often from subglacial lakes. The team found that the fastest-moving glaciers have a whole lot of water moving around underneath them, which speeds melting and lubricates the ice sheet so it slides faster, in turn melting even more ice. And those are just two of the most recent surveys. Look at any news site and its probably delivered the same gnarly message at some point recently: The glaciers are melting faster than previously realized. (Our site has one, too: Greenlands ice sheet is less stable than we thought, from 2016.) The new group is joining the race to better understand glaciers. Arte Glacier Initiative, a nonprofit research organization founded by scientists at MIT and Dartmouth, has already awarded its first grants to researchers looking into how glaciers melt and plans to study the possibility of reversing those fortunes, as James exclusively reported last week. Brent Minchew, one of the groups cofounders and an associate professor of geophysics at MIT, was drawn to studying glaciers because of their potential impact on sea-level rise. But over the years, I became less content with simply telling a more dramatic story about how things were goingand more open to asking the question of what can we do about it, he says. Minchew is among the researchers looking into potential plans to alter the future of glaciers. Strategies being proposed by groups around the world include building physical supports to prop them up and installing massive curtains to slow the flow of warm water that speeds melting. Another approach, which will be the focus of Arte, is called basal intervention. It basically involves drilling holes in glaciers, which would allow water flowing underneath the ice to be pumped out and refrozen, hopefully slowing them down. If you have questions about how all this would work, youre not alone. These are almost inconceivably huge engineering projects, theyd be expensive, and theyd face legal and ethical questions. Nobody really owns Antarctica, and its governed by a huge treatyhow could we possibly decide whether to move forward with these projects? Then theres the question of the potential side effects. Just look at recent news from the Arctic Ice Project, which was researching how to slow the melting of sea ice by covering it with substances designed to reflect sunlight away. (Sea ice is different from glaciers, but some of the key issues are the same.) One of the projects largest field experiments involved spreading tiny silica beads, sort of like sand, over 45,000 square feet of ice in Alaska. But after new research revealed that the materials might be disrupting food chains, the organization announced that its concluding its research and winding down operations. Cutting our emissions of greenhouse gases to stop climate change at the source would certainly be more straightforward than spreading beads on ice, or trying to stop a 74,000-square-mile glacier in its tracks. But were not doing so hot on cutting emissionsin fact, levels of carbon dioxide in the atmosphere rose faster than ever in 2024. And even if the world stopped polluting the atmosphere with planet-warming gases today, things may have already gone too far to save some of the most vulnerable glaciers. The longer I cover climate change and face the situation were in, the more I understand the impulse to at least consider every option out there, even if it sounds like science fiction.

Heading north in the dark, the only way Gavesh could try to track his progress through the Thai countryside was by watching the road signs zip by. The Jeeps three occupantsGavesh, a driver, and a young Chinese womanhad no languages in common, so they drove for hours in nervous silence as they wove their way out of Bangkok and toward Mae Sot, a city on Thailands western border with Myanmar. When they reached the city, the driver pulled off the road toward a small hotel, where another car was waiting. I had some suspicionslike, why are we changing vehicles? Gavesh remembers. But it happened so fast. They left the highway and drove on until, in total darkness, they parked at what looked like a private house. We stopped the vehicle. There were people gathered. Maybe 10 of them. They took the luggage and they asked us to come, Gavesh says. One was going in front, there was another one behind, and everyone said: Go, go, go. Gavesh and the Chinese woman were marched through the pitch-black fields by flashlight to a riverside where a boat was moored. By then, it was far too late to back out. Gaveshs journey had started, seemingly innocently, with a job ad on Facebook promising work he desperately needed. Instead, he found himself trafficked into a business commonly known as pig butcheringa form of fraud in which scammers form romantic or other close relationships with targets online and extract money from them. The Chinese crime syndicates behind the scams have netted billions of dollars, and they have used violence and coercion to force their workers, many of them people trafficked like Gavesh, to carry out the frauds from large compounds, several of which operate openly in the quasi-lawless borderlands of Myanmar. We spoke to Gavesh and five other workers from inside the scam industry, as well as anti-trafficking experts and technology specialists. Their testimony reveals how global companies, including American social media and dating apps and international cryptocurrency and messaging platforms, have given the fraud business the means to become industrialized. By the same token, it is Big Tech that may hold the key to breaking up the scam syndicatesif only these companies can be persuaded or compelled to act. Were identifying Gavesh using a pseudonym to protect his identity. He is from a country in South Asia, one he asked us not to name. He hasnt shared his story much, and he still hasnt told his family. He worries about how theyd handle it. Until the pandemic, he had held down a job in the tourism industry. But lockdowns had gutted the sector, and two years later he was working as a day laborer to support himself and his father and sister. I was fed up with my life, he says. I was trying so hard to find a way to get out. When he saw the Facebook post in mid-2022, it seemed like a godsend. A company in Thailand was looking for English-speaking customer service and data entry specialists. The monthly salary was $1,500far more than he could earn at homewith meals, travel costs, a visa, and accommodation included. I knew if I got this job, my life would turn around. I would be able to give my family a good life, Gavesh says. What came next was life-changing, but not in the way Gavesh had hoped. The advert was a fraudand a classic tactic syndicates use to force workers like Gavesh into an economy that operates as something like a dark mirror of the global outsourcing industry. The true scale of this type of fraud is hard to estimate, but the United Nations reported in 2023 that hundreds of thousands of people had been trafficked to work as online scammers in Southeast Asia. One 2024 study, from the University of Texas, estimates that the criminal syndicates that run these businesses have stolen at least $75 billion since 2020. These schemes have been going on for more than two decades, but theyve started to capture global attention only recently, as the syndicates running them increasingly shift from Chinese targets toward the West. And even as investigators, international organizations, and journalists gradually pull back the curtain on the brutal conditions inside scamming compounds and document their vast scale, what is far less exposed is the pivotal role platforms owned by Big Tech play throughout the industryfrom initially coercing individuals to become scammers to, finally, duping scam targets out of their life savings. As losses mount, governments and law enforcement agencies have looked for ways to disrupt the syndicates, which have become adept at using ungoverned spaces in lawless borderlands and partnering with corrupt regimes. But on the whole, the syndicates have managed to stay a step ahead of law enforcementin part by relying on services from the worlds tech giants. Apple iPhones are their preferred scamming tools. Meta-owned Facebook and WhatsApp are used to recruit people into forced labor, as is Telegram. Social media and messaging platforms, including Facebook, Instagram, WhatsApp, WeChat, and X, provide spaces for scammers to find and lure targets. So do dating apps, including Tinder. Some of the scam compounds have their own Starlink terminals. And cryptocurrencies like tether and global crypto platforms like Binance have allowed the criminal operations to move money with little or no oversight. Scam workers sit inside Myanmar's KK Park, a notorious fraud hub near the border with Thailand, following a recent crackdown by law enforcement.REUTERS Private-sector corporations are, unfortunately, inadvertently enabling this criminal industry, says Andrew Wasuwongse, the Thailand country director at the anti-trafficking nonprofit International Justice Mission (IJM). The private sector holds significant tools and responsibility to disrupt and prevent its further growth. Yet while the tech sector has, slowly, begun to roll out anti-scam tools and policies, experts in human trafficking, platform integrity, and cybercrime tell us that these measures largely focus on the downstream problem: the losses suffered by the victims of the scams. That approach overlooks the other set of victims, often from lower-income countries, at the far end of a fraud supply chain that is built on human miseryand on Big Tech. Meanwhile, the scams continue on a mass scale. Tech companies could certainly be doing more to crack down, the experts say. Even relatively small interventions, they argue, could start to erode the business model of the scam syndicates; with enough of these, the whole business could start to founder. The trick is: How do you make it unprofitable? says Eric Davis, a platform integrity expert and senior vice president of special projects at the Institute for Security and Technology (IST), a think tank in California. How do you create enough friction? That question is only becoming more urgent as many tech companies pull back on efforts to moderate their platforms, artificial intelligence supercharges scam operations, and the Trump administration signals broad support for deregulation of the tech sector while withdrawing support from organizations that study the scams and support the victims. All these trends may further embolden the syndicates. And even as the human costs keep building, global governments exert ineffectual pressureif any at allon the tech sector to turn its vast financial and technical resources against a criminal economy that has thrived in the spaces Silicon Valley built. Capturing a vulnerable workforce The roots of pig butchering scams reach back to the offshore gambling industry that emerged from China in the early 2000s. Online casinos had become hugely popular in China, but the government cracked down, forcing the operators to relocate to Cambodia, the Philippines, Laos, and Myanmar. There, they could continue to target Chinese gamblers with relative impunity. Over time, the casinos began to use social media to entice people back home, deploying scam-like tactics that frequently centered on attractive and even nude dealers. The doubts didnt really start until after Gavesh reached Bangkoks Suvarnabhumi Airport. As time ticked by, it began to occur to him that he was alone, with no money, no return ticket, and no working SIM card. Often the romance scam was a part of thatbuilding romantic relationships with people that you eventually would aim to hook, says Jason Tower, Myanmar country director at the United States Institute of Peace (USIP), a research and diplomacy organization funded by the US government, who researches the cyber scam industry. (USIPs leadership was recently targeted by the Trump administration and Elon Musks Department of Government Efficiency task force, leaving the organizations future uncertain; its website, which previously housed its research, is also currently offline.) By the late 2010s, many of the casinos were big, professional operations. Gradually, says Tower, the business model turned more sinister, with a tactic called sha zhu pan in Chinese emerging as a core strategy. Scamming operatives work to fatten up or cultivate a target by building a relationship before going in for the slaughterpersuading them to invest in a supposedly once-in-a-lifetime scheme and then absconding with the money. That actually ended up being much, much more lucrative than online gambling, Tower says. (The international law enforcement organization Interpol no longer uses the graphic term pig butchering, citing concerns that it dehumanizes and stigmatizes victims.) Like other online industries, the romance scamming business was supercharged by the pandemic. There were simply more isolated people to defraud, and more people out of work who might be persuaded to try scamming othersor who were vulnerable to being trafficked into the industry. Initially, most of the workers carrying out the frauds were Chinese, as were the fraud victims. But after the government in Beijing tightened travel restrictions, making it hard to recruit Chinese laborers, the syndicates went global. They started targeting more Western markets and turning, Tower says, to much more malign types of approaches to tricking people into scam centers. Getting recruited Gavesh was scrolling through Facebook when he saw the ad. He sent his rsum to a Telegram contact number. A human resources representative replied and had him demonstrate his English and typing skills over video. It all felt very professional. I didnt have any reason to suspect, he says. The doubts didnt really start until after he reached Bangkoks Suvarnabhumi Airport. After being met at arrivals by a man who spoke no English, he was left to wait. As time ticked by, it began to occur to Gavesh that he was alone, with no money, no return ticket, and no working SIM card. Finally, the Jeep arrived to pick him up. Hours later, exhausted, he was on a boat crossing the Moei River from Thailand into Myanmar. On the far bank, a group was waiting. One man was in military uniform and carried a gun. In my country, if we see an army guy when we are in trouble, we feel safe, Gavesh says. So my initial thoughts were: Okay, theres nothing to be worried about. They hiked a kilometer across a sodden paddy field and emerged at the other side caked in mud. There a van was parked, and the driver took them to what he called, in broken English, the office. They arrived at the gate of a huge compound, surrounded by high walls topped with barbed wire. While some people are drawn into online scamming directly by friends and relatives, Facebook is, according to IJMs Wasuwongse, the most common entry point for people recruited on social media. Meta has known for years that its platforms host this kind of content. Back in 2019, the BBC exposed slave markets that were running on Instagram; in 2021, the Wall Street Journal reported, drawing on documents leaked by a whistleblower, that Meta had long struggled to rein in the problem but took meaningful action only after Apple threatened to pull Instagram from its app store. Today, years on, ads like the one that Gavesh responded to are still easy to find on Facebook if you know what to look for. Examples of fraudulent Facebook ads, shared by International Justice Mission. They are typically posted in job seekers groups and usually seem to be advertising legitimate jobs in areas like customer service. They offer attractive wages, especially for people with language skillsusually English or Chinese. The traffickers tend to finish the recruitment process on encrypted or private messaging apps. In our research, many experts said that Telegram, which is notorious for hosting terrorist content, child sexual abuse material, and other communication related to criminal activity, was particularly problematic. Many spoke with a combination of anger and resignation about its apparent lack of interest in working with them to address the problem; Mina Chiang, founder of Humanity Research Consultancy, an anti-trafficking organization, accuses the app of being very much complicit in human trafficking and proactively facilitating these scams. (Telegram did not respond to a request for comment.) But while Telegram users have the option of encrypting their messages end to end, making them almost impossible to monitor, social media companies are of course able to access users posts. And its here, at the beginning of the romance scam supply chain, where Big Tech could arguably make its most consequential intervention. Social media is monitored by a combination of human moderators and AI systems, which help flag users and contentads, posts, pagesthat break the law or violate the companies own policies. Dangerous content is easiest to police when it follows predictable patterns or is posted by users acting in distinctive and suspicious ways. They have financial resources. You can hire the most talented coding engineers in the world. Why cant you just find people who understand the issue properly? Anti-trafficking experts say the scam advertising tends to follow formulaic templates and use common language, and that they routinely report the ads to Meta and point out the markers they have identified. Their hope is that this information will be fed into the data sets that train the content moderation models. While individual ads may be taken down, even in big waveslast November, Meta said it had purged 2 million accounts connected to scamming syndicates over the previous yearexperts say that Facebook still continues to be used in recruiting. And new ads keep appearing. (In response to a request for comment, a Meta spokesperson shared links to policies about bans on content or advertisements that facilitate human trafficking, as well as company blog posts telling users how to protect themselves from romance scams and sharing details about the companys efforts to disrupt fraud on its platforms, one statingthat it is constantly rolling out new product features to help protect people on [its] apps from known scam tactics at scale. The spokesperson also said that WhatsApp has spam detection technology, and millions of accounts are banned per month.) Anti-trafficking experts we spoke with say that as recently as last fall, Meta was engaging with them and had told them it was ramping up its capabilities. But Chiang says there still isnt enough urgency from tech companies. Theres a question about speed. They might be able to say Thats the goal for the next two years. No. But thats not fast enough. We need it now, she says. They have financial resources. You can hire the most talented coding engineers in the world. Why cant you just find people who understand the issue properly? Part of the answer comes down to money, according to experts we spoke with. Scaling up content moderation and other processes that could cause users to be kicked off a platform requires not only technological staff but also legal and policy expertswhich not everyone sees as worth the cost. The vast majority of these companies are doing the minimum or less, says Tower of USIP. If not properly incentivized, either through regulatory action or through exposure by media or other forms of pressure often, these companies will underinvest in keeping their platforms safe. Getting set up Gaveshs new office turned out to be one of the most infamous scamming hubs in Southeast Asia: KK Park in Myanmars Myawaddy region. Satellite imagery shows it as a densely packed cluster of buildings, surrounded by fields. Most of it has been built since late 2019. Inside, it runs like a hybrid of a company campus and a prison. When Gavesh arrived, he handed over his phone and passport and was assigned to a dormitory and an employer. He was allowed his own phone back only for short periods, and his calls were monitored. Security was tight. He had to pass through airport-style metal detectors when he went in or out of the office. Black-uniformed personnel patrolled the buildings, while armed men in combat fatigues watched the perimeter fences from guard posts. On his first full day, he was put in front of a computer with just four documents on it, which he had to read over and overguides on how to approach strangers. On his second day, he learned to build fake profiles on social media and dating apps. The trick was to find real people on Instagram or Facebook who were physically attractive, posted often, and appeared to be wealthy and living a luxurious life, he says, and use their photos to build a new account: There are so many Instagram models that pretend they have a lot of money. After Gavesh was trafficked into Myanmar, he was taken to KK Park. Most of the compound has been built since late 2019.LUKE DUGGLEBY/REDUX Next, he was given a batch of iPhone 8smost people on his team used between eight and 10 devices eachloaded with local SIM cards and apps that spoofed their location so that they appeared to be in the US. Using male and female aliases, he set up dozens of accounts on Facebook, WhatsApp, Telegram, Instagram, and X and profiles on several dating platforms, though he cant remember exactly which ones. Different scamming operations teach different techniques for finding and reaching out to potential victims, several people who worked in the compounds tell us. Some people used direct approaches on dating apps, Facebook, Instagram, orfor those targeting Chinese victimsWeChat. One worker from Myanmar sent out mass messages on WhatsApp, pretending to have accidentally messaged a wrong number, in the hope of striking up a conversation. (Tencent, which owns WeChat, declined to comment.) Some scamming workers we spoke to were told to target white, middle-aged or older men in Western countries who seemed to be well off. Gavesh says he would pretend to be white men and women, using information found from Google to add verisimilitude to his claims of living in, say, Miami Beach. He would chat with the targets, trying to figure out from their jobs, spending habits, and ambitions whether theyd be worth investing time in. One South African woman, trafficked to Myanmar in 2022, says she was given a script and told to pose as an Asian woman living in Chicago. She was instructed to study her assigned city and learn quotidian details about life there. They kept on punishing people all the time for not knowing or for forgetting that theyre staying in Chicago, she says, or for forgetting whats Starbucks or whats [a] latte. Fake users have, of course, been a problem on social media platforms and dating sites for years. Some platforms, such as X, allow practically anyone to create accounts and even to have them verified for a fee. Others, including Facebook, have periodically conducted sweeps to get rid of fake accounts engaged in what Meta calls coordinated inauthentic behavior. (X did not respond to requests for comment.) But scam workers tell us they were advised on simple ways to circumvent detection mechanisms on social media. They were given basic training in how to avoid suspicious behavior such as adding too many contacts too quickly, which might trigger the company to review whether someones profile is authentic. The South African woman says she was shown how to manipulate the dates on a Facebook account to seem as if you opened the account in 2019 or whatever, making it easier to add friends. (Metas spam filtersmeant to reduce the spread of unwanted contentinclude limits on friend requests and bulk messaging.) Wang set up a Tinder profile with a picture of a dog and a bio that read, I am a dog. It passed through the platforms verification system without a hitch. Dating apps, whose users generally hope to meet other users in real life, have a particular need to make sure that people are who they say they are. But Match Group, the parent company of Tinder, ended its partnership with a company doing background checks in 2023. It now encourages users to verify their profile with a selfie and further ID checks, though insiders say these systems are often rudimentary. They just check a box and [do] what is legally required or what will make the media get off of [their] case, says one tech executive who has worked with multiple dating apps on safety systems, speaking on the condition of anonymity because they were not permitted to speak about their work with certain companies. Fangzhou Wang, an assistant professor at the University of Texas at Arlington who studies romance scams, ran a test: She set up a Tinder profile with a picture of a dog and a bio that read, I am a dog. It passed through the platforms verification system without a hitch. They are not providing enough security measures to filter out fraudulent profiles, Wang says. Everybody can create anything. Like recruitment ads, the scam profiles tend to follow patterns that should raise red flags. They use photos copied from existing users or made by artificial intelligence, and the accounts are sometimes set up using phone numbers generated by voice-over-internet-protocol services. Then theres the scammers behavior: They swipe too fast, or spend too much time logged in. A normal human doesnt spend eight hours on a dating app a day, the tech executive says. Whats more, scammers use the same language over and over again as they reach out to potential targets. The majority of them are using predesigned scripts, says Wang. It would be fairly easy for platforms to detect these signs and either stop accounts from being created or make the users go through further checks, experts tell us. Signals of some of these behaviors can potentially be embedded into a type of machine-learning algorithm, Wang says. She approached Tinder a few years ago with her research into the language that scammers use on the platforms, and offered to help build data sets for its moderation models. She says the company didnt reply. (In a statement, Yoel Roth, vice president of trust and safety at Match Group, said that the company invests in proactive tools, advanced detection systems and user education to help prevent harm. He wrote, We use proprietary AI-powered tools to help identify scammer messaging, and unlike many platforms, we moderate messages, which allows us to detect suspicious patterns early and act quickly, adding that the company has recently worked with Reality Defender, a provider of deepfake detection tools, to strengthen its ability to detect AI-generated content. A company spokesperson reported having no record of Wangs outreach but said that the company welcome[s] collaboration and [is] always open to reviewing research that can help strengthen user safety.) A recent investigation published in The Markup found that Match Group has long possessed the tools and resources to track sex offenders and other bad actors but has resisted efforts to roll out safety protocols for fear they might slow growth. This tension, between the desire to keep increasing the number of users and the need to ensure that these users and their online activity are authentic, is often behind safety issues on platforms. While no platform wants to be a haven for fraudsters, identity verification creates friction for users, which stops real people as well as impostors from signing up. And again, cracking down on platform violations costs money. According to Josh Kim, an economist who works in Big Tech, it would be costly for tech companies to build out the legal, policy, and operational teams for content moderation tools that could get users kicked off a platformand the expense is one companies may find hard to justify in the current business climate. The shift toward profitability means that you have to be very selective in where you invest the resources that you have, he says. My intuition here is that unless there are fines or pressure from governments or regulatory agencies or the public themselves, he adds, the current atmosphere in the tech ecosystem is to focus on building a product that is profitable and grows fast, and things that dont contribute to those two points are probably being deprioritized. Getting onlineand staying in line At work, Gavesh wore a blue tag, marking him as belonging to the lowest rank of workers. On top of us are the ones who are wearing the yellow tagsthey call themselves HR or translators, or office guys, he says. Red tags are team leaders, managers And then moving from that, they have black and ash tags. Those are the ones running the office. Most of the latter were Chinese, Gavesh says, as were the really big bosses, who didnt wear tags at all. Within this hierarchy operated a system of incentives and punishments. Workers who followed orders and proved successful at scamming could rise through the ranks to training or supervisory positions, and gain access to perks like restaurants and nightclubs. Those who failed to meet the targets or broke the rules faced violence and humiliation. Gavesh says he was once beaten because he broke an unwritten rule that it was forbidden to cross your legs at work. Yawning was banned, and bathroom breaks were limited to two minutes at a time. KATHERINE LAM Beatings were usually conducted in the open, though the most severe punishments at Gaveshs company happened in a room called the water jail. One day a coworker was there alongside the others, and the next day he was not, Gavesh recalls. When the colleague was brought back to the office, he had been so badly beaten he couldnt walk or speak. They took him to the front, and they said: If you do not listen to us, this is what will happen to you. Gavesh was desperate to leave but felt there was no chance of escaping. The armed guards seemed ready to shoot, and there were rumors in the compound that some people who jumped the fence had been found drowned in the river. This kind of physical and psychological abuse is routine across the industry. Gavesh and others we spoke to describe working 12 hours or more a day, without days off. They faced strict quotas for the number of scam targets they had to have on the hook. If they failed to reach them, they were punished. The UN has documented cases of torture, arbitrary detention, and sexual violence in the compounds. We h

While AI models are certainly capable of creating interesting and sometimes entertaining material, their output isnt necessarily useful. Google DeepMind is hoping that its new robotics model could make machines more receptive to verbal commands, paving the way for us to simply speak orders to them aloud.

And burnt-out coders are allowing AI to take the wheel entirely in a new practice dubbed vibe coding.

A year or so ago, Xiao Li was seeing floods of Nvidia chip deals on WeChat. A real estate contractor turned data center project manager, he had pivoted to AI infrastructure in 2023, drawn by the promise of Chinas AI craze. At that time, traders in his circle bragged about securing shipments of high-performing Nvidia GPUs that were subject to US export restrictions. Many were smuggled through overseas channels to Shenzhen. At the height of the demand, a single Nvidia H100 chip, a kind that is essential to training AI models, could sell for up to 200,000 yuan ($28,000) on the black market. Now, his WeChat feed and industry group chats tell a different story. Traders are more discreet in their dealings, and prices have come back down to earth. Meanwhile, two data center projects Li is familiar with are struggling to secure further funding from investors who anticipate poor returns, forcing project leads to sell off surplus GPUs. It seems like everyone is selling, but few are buying, he says. Just months ago, a boom in data center construction was at its height, fueled by both government and private investors. However, many newly built facilities are now sitting empty. According to people on the ground who spoke to MIT Technology Reviewincluding contractors, an executive at a GPU server company, and project managersmost of the companies running these data centers are struggling to stay afloat. The local Chinese outlets Jiazi Guangnian and 36Kr report that up to 80% of Chinas newly built computing resources remain unused. Renting out GPUs to companies that need them for training AI modelsthe main business model for the new wave of data centerswas once seen as a sure bet. But with the rise of DeepSeek and a sudden change in the economics around AI, the industry is faltering. The growing pain Chinas AI industry is going through is largely a result of inexperienced playerscorporations and local governmentsjumping on the hype train, building facilities that arent optimal for todays need, says Jimmy Goodrich, senior advisor for technology at the RAND Corporation. The upshot is that projects are failing, energy is being wasted, and data centers have become distressed assets whose investors are keen to unload them at below-market rates. The situation may eventually prompt government intervention, he says: The Chinese government is likely to step in, take over, and hand them off to more capable operators. A chaotic building boom When ChatGPT exploded onto the scene in late 2022, the response in China was swift. The central government designated AI infrastructure as a national priority, urging local governments to accelerate the development of so-called smart computing centersa term coined to describe AI-focused data centers. In 2023 and 2024, over 500 new data center projects were announced everywhere from Inner Mongolia to Guangdong, according to KZ Consulting, a market research firm. According to the China Communications Industry Association Data Center Committee, a state-affiliated industry association, at least 150 of the newly built data centers were finished and running by the end of 2024. State-owned enterprises, publicly traded firms, and state-affiliated funds lined up to invest in them, hoping to position themselves as AI front-runners. Local governments heavily promoted them in the hope theyd stimulate the economy and establish their region as a key AI hub. However, as these costly construction projects continue, the Chinese frenzy over large language models is losing momentum. In 2024 alone, over 144 companies registered with the Cyberspace Administration of Chinathe country's central internet regulatorto develop their own LLMs. Yet according to the Economic Observer, a Chinese publication, only about 10% of those companies were still actively investing in large-scale model training by the end of the year. Chinas political system is highly centralized, with local government officials typically moving up the ranks through regional appointments. As a result, many local leaders prioritize short-term economic projects that demonstrate quick resultsoften to gain favor with higher-upsrather than long-term development. Large, high-profile infrastructure projects have long been a tool for local officials to boost their political careers. The post-pandemic economic downturn only intensified this dynamic. With Chinas real estate sectoronce the backbone of local economiesslumping for the first time in decades, officials scrambled to find alternative growth drivers. In the meantime, the countrys once high-flying internet industry was also entering a period of stagnation. In this vacuum, AI infrastructure became the new stimulus of choice. AI felt like a shot of adrenaline, says Li. A lot of money that used to flow into real estate is now going into AI data centers. By 2023, major corporationsmany of them with little prior experience in AIbegan partnering with local governments to capitalize on the trend. Some saw AI infrastructure as a way to justify business expansion or boost stock prices, says Fang Cunbao, a data center project manager based in Beijing. Among them were companies like Lotus, an MSG manufacturer, and Jinlun Technology, a textile firmhardly the names one would associate with cutting-edge AI technology. This gold-rush approach meant that the push to build AI data centers was largely driven from the top down, often with little regard for actual demand or technical feasibility, say Fang, Li, and multiple on-the-ground sources, who asked to speak anonymously for fear of political repercussions. Many projects were led by executives and investors with limited expertise in AI infrastructure, they say. In the rush to keep up, many were constructed hastily and fell short of industry standards. Putting all these large clusters of chips together is a very difficult exercise, and there are very few companies or individuals who know how to do it at scale, says Goodrich. This is all really state-of-the-art computer engineering. Id be surprised if most of these smaller players know how to do it. A lot of the freshly built data centers are quickly strung together and dont offer the stability that a company like DeepSeek would want. To make matters worse, project leaders often relied on middlemen and brokerssome of whom exaggerated demand forecasts or manipulated procurement processes to pocket government subsidies, sources say. By the end of 2024, the excitement that once surrounded Chinas data center boom was curdling into disappointment. The reason is simple: GPU rental is no longer a particularly lucrative business. The DeepSeek reckoning The business model of data centers is in theory straightforward: They make money by renting out GPU clusters to companies that need computing capacity for AI training. In reality, however, securing clients is proving difficult. Only a few top tech companies in China are now drawing heavily on computing power to train their AI models. Many smaller players have been giving up on pretraining their models or otherwise shifting their strategy since the rise of DeepSeek, which broke the internet with R1, its open-source reasoning model that matches the performance of ChatGPT o1 but was built at a fraction of its cost. DeepSeek is a moment of reckoning for the Chinese AI industry. The burning question shifted from Who can make the best large language model? to Who can use them better? says Hangcheng Cao, an assistant professor of information systems at Emory University. The rise of reasoning models like DeepSeeks R1 and OpenAIs ChatGPT o1 and o3 has also changed what businesses want from a data center. With this technology, most of the computing needs come from conducting step-by-step logical deductions in response to users queries, not from the process of training and creating the model in the first place. This reasoning process often yields better results but takes significantly more time. As a result, hardware with low latency (the time it takes for data to pass from one point on a network to another) is paramount. Data centers need to be located near major tech hubs to minimize transmission delays and ensure access to highly skilled operations and maintenance staff. This change means many data centers built in central, western, and rural Chinawhere electricity and land are cheaperare losing their allure to AI companies. In Zhengzhou, a city in Lis home province of Henan, a newly built data center is even distributing free computing vouchers to local tech firms but still struggles to attract clients. Additionally, a lot of the new data centers that have sprung up in recent years were optimized for pretraining workloadslarge, sustained computations run on massive data setsrather than for inference, the process of running trained reasoning models to respond to user inputs in real time. Inference-friendly hardware differs from whats traditionally used for large-scale AI training. GPUs like Nvidia H100 and A100 are designed for massive data processing, prioritizing speed and memory capacity. But as AI moves toward real-time reasoning, the industry seeks chips that are more efficient, responsive, and cost-effective. Even a minor miscalculation in infrastructure needs can render a data center suboptimal for the tasks clients require. In these circumstances, the GPU rental price has dropped to an all-time low. A recent report from the Chinese media outlet Zhineng Yongxian said that an Nvidia H100 server configured with eight GPUs now rents for 75,000 yuan per month, down from highs of around 180,000. Some data centers would rather leave their facilities sitting empty than run the risk of losing even more money because they are so costly to run, says Fan: The revenue from having a tiny part of the data center running simply wouldnt cover the electricity and maintenance cost. Its paradoxicalChina faces the highest acquisition costs for Nvidia chips, yet GPU leasing prices are extraordinarily low, Li says. Theres an oversupply of computational power, especially in central and west China, but at the same time, theres a shortage of cutting-edge chips. However, not all brokers were looking to make money from data centers in the first place. Instead, many were interested in gaming government benefits all along. Some operators exploit the sector for subsidized green electricity, obtaining permits to generate and sell power, according to Fang and some Chinese media reports. Instead of using the energy for AI workloads, they resell it back to the grid at a premium. In other cases, companies acquire land for data center development to qualify for state-backed loans and credits, leaving facilities unused while still benefiting from state funding, according to the local media outlet Jiazi Guangnian. Towards the end of 2024, no clear-headed contractor and broker in the market would still go into the business expecting direct profitability, says Fang. Everyone I met is leveraging the data center deal for something else the government could offer. A necessary evil Despite the underutilization of data centers, Chinas central government is still throwing its weight behind a push for AI infrastructure. In early 2025, it convened an AI industry symposium, emphasizing the importance of self-reliance in this technology. Major Chinese tech companies are taking note, making investments aligning with this national priority. Alibaba Group announced plans to invest over $50 billion in cloud computing and AI hardware infrastructure over the next three years, while ByteDance plans to invest around $20 billion in GPUs and data centers. In the meantime, companies in the US are doing likewise. Major tech firms including OpenAI, Softbank, and Oracle have teamed up to commit to the Stargate initiative, which plans to invest up to $500 billion over the next four years to build advanced data centers and computing infrastructure. Given the AI competition between the two countries, experts say that China is unlikely to scale back its efforts. If generative AI is going to be the killer technology, infrastructure is going to be the determinant of success, says Goodrich, the tech policy advisor to RAND. The Chinese central government will likely see [underused data centers] as a necessary evil to develop an important capability, a growing pain of sorts. You have the failed projects and distressed assets, and the state will consolidate and clean it up. They see the end, not the means, Goodrich says. Demand remains strong for Nvidia chips, and especially the H20 chip, which was custom-designed for the Chinese market. One industry source, who requested not to be identified under his company policy, confirmed that the H20, a lighter, faster model optimized for AI inference, is currently the most popular Nvidia chip, followed by the H100, which continues to flow steadily into China even though sales are officially restricted by US sanctions. Some of the new demand is driven by companies deploying their own versions of DeepSeeks open-source models. For now, many data centers in China sit in limbobuilt for a future that has yet to arrive. Whether they will find a second life remains uncertain. For Fang Cunbao, DeepSeeks success has become a moment of reckoning, casting doubt on the assumption that an endless expansion of AI infrastructure guarantees progress. Thats just a myth, he now realizes. At the start of this year, Fang decided to quit the data center industry altogether. The market is too chaotic. The early adopters profited, but now its just people chasing policy loopholes, he says. Hes decided to go into AI education next. What stands between now and a future where AI is actually everywhere, he says, is not infrastructure anymore, but solid plans to deploy the technology.

OpenAI has released a new image generator thats designed less for typical surrealist AI art and more for highly controllable and practical creation of visualsa sign that OpenAI thinks its tools are ready for use in fields like advertising and graphic design. The image generator, which is now part of the companys GPT-4o model, was promised by OpenAI last May but wasnt released. Requests for generated images on ChatGPT were filled by an older image generator called DALL-E. OpenAI has been tweaking the new model since then and will now release it over the coming weeks to all tiers of users starting today, replacing the older one. The new model makes progress on technical issues that have plagued AI image generators for years. While most have been great at creating fantastical images or realistic deepfakes, theyve been terrible at something called binding, which refers to the ability to identify certain objects correctly and put them in their proper place (like a sign that says hot dogs properly placed above a food cart, not somewhere else in the image). It was only a few years ago that models started to succeed at things like Put the red cube on top of the blue cube, a feature that is essential for any creative professional use of AI. Generators also struggle with text generation, typically creating distorted jumbles of letter shapes that look more like captchas than readable text. Example images from OpenAI show progress here. The model is able to generate 12 discrete graphics within a single imagelike a cat emoji or a lightning boltand place them in proper order. Another shows four cocktails accompanied by recipe cards with accurate, legible text. More images show comic strips with text bubbles, mock advertisements, and instructional diagrams. The model also allows you to upload images to be modified, and it will be available in the video generator Sora as well as in GPT-4o. Its a new tool for communication, says Gabe Goh, the lead designer on the generator at OpenAI. Kenji Hata, a researcher at OpenAI who also worked on the tool, puts it a different way: I think the whole idea is that were going away from, like, beautiful art. It can still do that, he clarifies, but it will do more useful things too. You can actually make images work for you, he says, and not just just look at them. Its a clear sign that OpenAI is positioning the tool to be used more by creative professionals: think graphic designers, ad agencies, social media managers, or illustrators. But in entering this domain, OpenAI has two paths, both difficult. One, it can target the skilled professionals who have long used programs like Adobe Photoshop, which is also investing heavily in AI tools that can fill images with generative AI. Adobe really has a stranglehold on this market, and theyre moving fast enough that I dont know how compelling it is for people to switch, says David Raskino, the cofounder and chief technical officer of Irreverent Labs, which works on AI video generation. The second option is to target casual designers who have flocked to tools like Canva (which has also been investing in AI). This is an audience that may not have ever needed technically demanding software like Photoshop but would use more casual design tools to create visuals. To succeed here, OpenAI would have to lure people away from platforms built for design in hopes that the speed and quality of its own image generator would make the switch worth it (at least for part of the design process). Its also possible the tool will simply be used as many image generators are now: to create quick visuals that are good enough to accompany social media posts. But with OpenAI planning massive investments, including participation in the $500 billion Stargate project to build new data centers at unprecedented scale, its hard to imagine that the image generator wont play some ambitious moneymaking role. Regardless, the fact that OpenAIs new image generator has pushed through notable technical hurdles has raised the bar for other AI companies. Clearing those hurdles likely required lots of very specific data, Raskino says, like millions of images in which text is properly displayed at lots of different angles and orientations. Now competing image generators will have to match those achievements to keep up. The pace of innovation should increase here, Raskino says.

This is today's edition ofThe Download,our weekday newsletter that provides a daily dose of what's going on in the world of technology. Ethically sourced spare human bodies could revolutionize medicine Many challenges in medicine stem, in large part, from a common root cause: a severe shortage of ethically-sourced human bodies. There might be a way to get out of this moral and scientific deadlock. Recent advances in biotechnology now provide a pathway to producing living human bodies without the neural components that allow us to think, be aware, or feel pain.Many will find this possibility disturbing, but if researchers and policymakers can find a way to pull these technologies together, we may one day be able to create spare bodies, both human and nonhuman. These could revolutionize medical research and drug development, greatly reducing the need for animal testing, rescuing many people from organ transplant lists, and allowing us to produce more effective drugs and treatments. All without crossing most peoples ethical lines.

The big story How AI is changing gymnastics judging January 2024 The 2023 World Championships last October marked the first time an AI judging system was used on every apparatus in a gymnastics competition. There are obvious upsides to using this kind of technology: AI could help take the guesswork out of the judging technicalities. It could even help to eliminate biases, making the sport both more fair and more transparent. At the same time, others fear AI judging will take away something that makes gymnastics special. Gymnastics is a subjective sport, like diving or dressage, and technology could eliminate the judges role in crafting a narrative. For better or worse, AI has officially infiltrated the world of gymnastics. The question now is whether it really makes it fairer. Read the full story.

This story was originally published in October 2024. In March 2025, 23andMe filed for bankruptcy and announced its plans to facilitate a sale process to maximize the value of its business. MIT Technology Review'sHow Toseries helps you get things done. Things arent looking good for 23andMe. The consumer DNA testing company recently parted ways with all its board members but CEO Anne Wojcicki over her plans to take the company private. Its also still dealing with the fallout of a major security breach last October, which saw hackers access the personal data of around 5.5 million customers. 23andMes business is built on taking saliva samples from its customers. The DNA from those samples is processed and analyzed in its labs to produce personalized genetic reports detailing a users unique health and ancestry. The uncertainty swirling around the companys future and potential new ownership has prompted privacy campaigners to urge users to delete their data. Its not just you. If anyone in your family gave their DNA to 23&Me, for all of your sakes, close your/their account now, Meredith Whittaker, president of the encrypted messaging platform Signal, posted on X after the boards resignation. "Customers should consider current threats to their privacy as well as threats that may exist in the futuresome of which may be magnified if 23AndMe were sold to a new owner," says Jason Kelley, activism director at the Electronic Frontier Foundation. "23AndMe has protections around this much of this. But a potential sale could put your data in the hands of a far less scrupulous company." A spokesperson for 23andMe said that the company has strong customer privacy protections in place, and does not share customer data with third parties without customers consent. "Our research program is opt-in, requiring customers to go through a separate, informed consent process before joining," they say. We are committed to protecting customer data and are consistently focused on maintaining the privacy of our customers. That will not change. Why deleting your account comes with a caveat Deleting your data from 23andMe is permanent and cannot be reversed. But some of that data will be retained to comply with the companys legal obligations, according to its privacy statement. That means 23andMe and its third-party genotyping laboratory will hang onto some of your genetic information, plus your date of birth and sexalongside data linked to your account deletion request, including your email address and deletion request identifier. When MIT Technology Review asked 23andMe about the nature of the genetic information it retains, it referred us to its privacy policy but didn't provide any other details. Any information youve previously provided and consented to being used in 23andMe research projects also cannot be removed from ongoing or completed studies, although it will not be used in any future ones. Beyond the laboratories that process the saliva samples, the company does not share customer information with anyone else unless the user has given permission for it to do so, the spokesperson says, including employers, insurance companies, law enforcement agencies, or any public databases. We treat law enforcement inquiries, such as a valid subpoena or court order, with the utmost seriousness. We use all legal measures to resist any and all requests in order to protect our customer's privacy, the spokesperson says. To date, we have successfully challenged these requests and have not released any information to law enforcement. For those who still want their data deleted, heres how you go about it. How to delete your data from 23andMe Log into your account and navigate to Settings. Under Settings, scroll to the section titled 23andMe data. Select View. You may be asked to enter your date of birth for extra security. In the next section, youll be asked which, if any, personal data youd like to download from the company (onto a personal, not public, computer). Once youre finished, scroll to the bottom and select Permanently delete data. You should then receive an email from 23andMe detailing its account deletion policy and requesting that you confirm your request. Once you confirm youd like your data to be deleted, the deletion will begin automatically and youll immediately lose access to your account. What about your genetic sample? When you set up your 23andMe account, youre given the option either to have your saliva sample securely destroyed or to have it stored for future testing. If youve previously opted to store your sample but now want to delete your 23andMe account, the company says, it will destroy the sample for you as part of the account deletion process. What if you want to keep your genetic data, just not on 23andMe? Even if you want your data taken off 23AndMe, there are reasons why you might still want to have it hosted on other DNA sitesfor genealogical research, for example. And some people like the idea of having their DNA results stored on more than one database in case something happens to any one company. This is where downloading your data comes into play. FamilyTreeDNA, MyHeritage, GEDmatch, and Living DNA are among the DNA testing companies that allow you to upload existing DNA results from other companies, although Ancestry and 23andMe dont accept uploads. How to download your raw genetic data Navigate directly to you.23andme.com/tools/data/. Click on your profile name on the top right-hand corner. Then select Resources from the menu. Select Browse raw genotyping data and then Download. Visit Account settings and click on View under 23andMe data. Enter your date of birth for security purposes. Tick the box indicating that you understand the limitations and risks associated with uploading your information to third-party sites and press Submit request. 23andMe warns its users that uploading their data to other services could put genetic data privacy at risk. For example, bad actors could use someone elses DNA data to create fake genetic profiles. They could use these profiles to match with a relative and access personal identifying information and specific DNA variantssuch as information about any disease risk variants you might carry, the spokesperson says, adding: This is one reason why we dont support uploading DNA to 23andMe at this time. Update: This article has been updated to reflect that when asked about the nature of the genetic information it retains, 23andMe referred us to its privacy policy but didn't provide any other details.

Why do we hear about medical breakthroughs in mice, but rarely see them translate into cures for human disease? Why do so few drugs that enter clinical trials receive regulatory approval? And why is the waiting list for organ transplantation so long? These challenges stem in large part from a common root cause: a severe shortage of ethically-sourced human bodies. It may be disturbing to characterize human bodies in such commodifying terms, but the unavoidable reality is that human biological materials are an essential commodity in medicine, and persistent shortages of these materials create a major bottleneck to progress. This imbalance between supply and demand is the underlying cause of the organ shortage crisis, with more than 100,000 patients currently waiting for a solid organ transplant in the US alone. It also forces us to rely heavily on animals in medical research, a practice that cant replicate major aspects of human physiology and necessitates the infliction of harm to sentient creatures. In addition, the safety and efficacy of any experimental drug must still be confirmed in clinical trials on living human bodies. These costly trials risk harm to patients, can take a decade or longer to complete, and make it through to approval less than 15% of the time. There might be a way to get out of this moral and scientific deadlock. Recent advances in biotechnology now provide a pathway to producing living human bodies without the neural components that allow us to think, be aware, or feel pain. Many will find this possibility disturbing, but if researchers and policymakers can find a way to pull these technologies together, we may one day be able to create spare bodies, both human and nonhuman. These could revolutionize medical research and drug development, greatly reducing the need for animal testing, rescuing many people from organ transplant lists, and allowing us to produce more effective drugs and treatments. All without crossing most peoples ethical lines. Bringing technologies together Although it may seem like science fiction, recent technological progress has pushed this concept into the realm of plausibility. Pluripotent stem cells, one of the earliest cell types to form during development, can give rise to every type of cell in the adult body. Recently, researchers have used these stem cells to create structures that seem to mimic the early development of actual human embryos. At the same time, artificial uterus technology is rapidly advancing, and other pathways may be opening to allow for the development of fetuses outside of the body. By integrating these different technologies and using established genetic techniques to inhibit brain development, it is possible to envision the creation of bodyoids a potentially unlimited source of human bodies, developed entirely outside of a human body from stem cells, that lack sentience or the ability to feel pain. There are still many technical roadblocks to achieving this vision, but we have reason to expect that bodyoids couldradically transform biomedical research by addressing critical limitations in the current models of research, drug development and medicine. Among many other benefits, theywould offer an almost unlimited source of organs, tissues and cells for use in transplantation. It could even be possible to generate organs directly from a patient's own cells, essentially cloning their biological material to ensure that transplanted tissues are a perfect immunological match to a patient and thus eliminating the need for lifelong immunosuppression. Bodyoids developed from a patient's cells could also allow for personalized screening of drugs, allowing physicians to directly assess the effect of different interventions in a biological model that accurately reflects a patient's own personal genetics and physiology. We can even envision using animal bodyoidsin agriculture, as a substitute for the use of sentient animal species. Of course, exciting possibilities are not certainties. We do not know whether the embryo models recently created from stem cells could give rise to living people or, thus far, even to living mice. We do not know when, or whether, an effective technique will be found for successfully gestating human bodies entirely outside a person. We cannot be sure whether such bodyoids can survive without ever having developed brains or the parts of brains associated with consciousness, or whether they would still serve as accurate models for living people without those brain functions. Even if it all works, it may not be practical or economical to grow bodyoids, possibly for many years, until they can be mature enough to be useful for our ends. Each of these questions will require substantial research and time. But we believe this idea is now plausible enough to justify discussing both the technical feasibility and ethical implications. Ethical considerations and societal implications Bodyoids could address many ethical problems in modern medicine, offering ways to avoid unnecessary pain and suffering. For example, they could offer an ethical alternative to the way we currently use nonhuman animals for research and food, providing meat or other products with no animal suffering or awareness. But when we come to human bodyoids, the issues become harder. Many will find the concept grotesque or appalling. And for good reason. We have an innate respect for human life in all its forms. We do not allow broad research on people who no longer have consciousness or, in some cases, never had it. At the same time, we know much can be gained from studying the human body. We learn much from the bodies of the dead, which these days are used for teaching and research only with consent. In laboratories, we study cells and tissues that were taken, with consent, from the bodies of the dead and the living. Recently we have even begun using for experiments the animated cadavers of people who have been declared legally dead, who have lost all brain function but whose other organs continue to function with mechanical assistance. Genetically modified pig kidneys have been connected to, or transplanted into, these legally dead but physiologically active cadavers to help researchers determine whether they would work in living people. In all these cases, nothing was, legally, a living human being at the time it was used for research. Human bodyoids would also fall into that category. But there are still a number of issues worth considering. The first is consent: The cells used to make bodyoids would have to come from someone, and wed have to make sure that this someone consented to this particular, likely controversial, use. But perhaps the deepest issue is that bodyoids might diminish the human status of real people who lack consciousness or sentience. Thus far, we have held to a standard that requires us to treat all humans born alive as people, entitled to life and respect. Would bodyoidscreated without pregnancy, parental hopes, or indeed parentsblur that line? Or would we consider a bodyoid a human being, entitled to the same respect? If so, whyjust because it looks like us? A sufficiently detailed mannequin can meet that test. Because it looks like us and is alive? Because it is alive and has our DNA? These are questions that will require careful thought. A call to action Until recently, the idea of making something like a bodyoid would have been relegated to the realms of science fiction and philosophical speculation. But now it is at least plausibleand possibly revolutionary. It is time for it to be explored. The potential benefitsfor both human patients and sentient animal speciesare great. Governments, companies and private foundations should start thinking about bodyoids as a possible path for investment.There is no need to start with humanswe can begin exploring the feasibility of this approach with rodents or other research animals. As we proceed, the ethical and social issues are at least as important as the scientific ones. Just because something can be done does not mean it should be done. Even if it looks possible, determining whether we should make bodyoids, nonhuman or human, will require considerable thought, discussion, and debate. Some of that will be by scientists, ethicists, and others with special interest or knowledge. But ultimately, the decisions will be made by societies and governments. The time to start those discussions is now, when a scientific pathway seems clear enough for us to avoid pure speculation but before the world is presented with a troubling surprise. The announcement of the birth of Dolly the cloned sheep back in the 1990s launched a hysterical reaction, complete with speculation about armies of cloned warrior slaves. Good decisions require more preparation. The path toward realizing the potential of bodyoids will not be without challenges; indeed, it may never be possible to get there, or even if it is possible, the path may never be taken. Caution is warranted, but so is bold vision; the opportunity is too important to ignore. Carsten T.

This story originally appeared in The Algorithm, our weekly newsletter on AI. To get stories like this in your inbox first,sign up here. This weeks edition of The Algorithm is brought to you not by your usual host, James ODonnell, but Eileen Guo, an investigative reporter at MIT Technology Review. A few weeks ago, when I was at the digital rights conference RightsCon in Taiwan, I watched in real time as civil society organizations from around the world, including the US, grappled with the loss of one of the biggest funders of global digital rights work: the United States government. As I wrote in my dispatch, the Trump administration's shocking, rapid gutting of the US government (and its push into what some prominent political scientists call competitive authoritarianism) also affects the operations and policies of American tech companiesmany of which, of course, have users far beyond US borders. People at RightsCon said they were already seeing changes in these companies willingness to engage with and invest in communities that have smaller user basesespecially non-English-speaking ones. As a result, some policymakers and business leadersin Europe, in particularare reconsidering their reliance on US-based tech and asking whether they can quickly spin up better, homegrown alternatives. This is particularly true for AI. One of the clearest examples of this is in social media. Yasmin Curzi, a Brazilian law professor who researches domestic tech policy, put it to me this way: Since Trumps second administration, we cannot count on [American social media platforms] to do even the bare minimum anymore. Social media content moderation systemswhich already use automation and are also experimenting with deploying large language models to flag problematic postsare failing to detect gender-based violence in places as varied as India, South Africa, and Brazil. If platforms begin to rely even more on LLMs for content moderation, this problem will likely get worse, says Marlena Wisniak, a human rights lawyer who focuses on AI governance at the European Center for Not-for-Profit Law. The LLMs are moderated poorly, and the poorly moderated LLMs are then also used to moderate other content, she tells me. Its so circular, and the errors just keep repeating and amplifying. Part of the problem is that the systems are trained primarily on data from the English-speaking world (and American English at that), and as a result, they perform less well with local languages and context. Even multilingual language models, which are meant to process multiple languages at once, still perform poorly with non-Western languages. For instance, one evaluation of ChatGPTs response to health-care queries found that results were far worse in Chinese and Hindi, which are less well represented in North American data sets, than in English and Spanish. For many at RightsCon, this validates their calls for more community-driven approaches to AIboth in and out of the social media context. These could include small language models, chatbots, and data sets designed for particular uses and specific to particular languages and cultural contexts. These systems could be trained to recognize slang usages and slurs, interpret words or phrases written in a mix of languages and even alphabets, and identify reclaimed language (onetime slurs that the targeted group has decided to embrace). All of these tend to be missed or miscategorized by language models and automated systems trained primarily on Anglo-American English. The founder of the startup Shhor AI, for example, hosted a panel at RightsCon and talked about its new content moderation API focused on Indian vernacular languages. Many similar solutions have been in development for yearsand weve covered a number of them, including a Mozilla-facilitated volunteer-led effort to collect training data in languages other than English, and promising startups like Lelapa AI, which is building AI for African languages. Earlier this year, we even included small language models on our 2025 list of top 10 breakthrough technologies. Still, this moment feels a little different. The second Trump administration, which shapes the actions and policies of American tech companies, is obviously a major factor. But there are others at play. First, recent research and development on language models has reached the point where data set size is no longer a predictor of performance, meaning that more people can create them. In fact, smaller language models might be worthy competitors of multilingual language models in specific, low-resource languages, says Aliya Bhatia, a visiting fellow at the Center for Democracy & Technology who researches automated content moderation. Then theres the global landscape. AI competition was a major theme of the recent Paris AI Summit, which took place the week before RightsCon. Since then, theres been a steady stream of announcements about sovereign AI initiatives that aim to give a country (or organization) full control over all aspects of AI development. AI sovereignty is just one part of the desire for broader tech sovereignty thats also been gaining steam, growing out of more sweeping concerns about the privacy and security of data transferred to the United States. The European Union appointed its first commissioner for tech sovereignty, security, and democracy last November and has been working on plans for a Euro Stack, or digital public infrastructure. The definition of this is still somewhat fluid, but it could include the energy, water, chips, cloud services, software, data, and AI needed to support modern society and future innovation. All these are largely provided by US tech companies today. Europes efforts are partly modeled after India Stack, that countrys digital infrastructure that includes the biometric identity system Aadhaar. Just last week, Dutch lawmakers passed several motions to untangle the country from US tech providers. This all fits in with what Andy Yen, CEO of the Switzerland-based digital privacy company Proton, told me at RightsCon. Trump, he said, is causing Europe to move faster to come to the realization that Europe needs to regain its tech sovereignty. This is partly because of the leverage that the president has over tech CEOs, Yen said, and also simply because tech is where the future economic growth of any country is. But just because governments get involved doesnt mean that issues around inclusion in language models will go away. I think there needs to be guardrails about what the role of the government here is. Where it gets tricky is if the government decides These are the languages we want to advance or These are the types of views we want represented in a data set, Bhatia says. Fundamentally, the training data a model trains on is akin to the worldview it develops. Its still too early to know what this will all look like, and how much of it will prove to be hype. But no matter what happens, this is a space well be watching. Now read the rest of The Algorithm Deeper Learning OpenAI has released its first research into how using ChatGPT affects peoples emotional well-being OpenAI released two pieces of research last week that explore how ChatGPT affects people who engage with it on emotional issues, yielding some interesting results. Female study participants were slightly less likely to socialize with people than their male counterparts who used the chatbot for the same period of time, our reporter Rhiannon Williams writes. And people who used voice mode in a gender that was not their own reported higher levels of loneliness at the end of the experiment. Why it matters: AI companies have raced to build chatbots that act not just as productivity tools but also as companions, romantic partners, friends, therapists, and more. Legally, its largely still a Wild West landscape. Some have instructed users to harm themselves, and others have offered sexually charged conversations as underage characters represented by deepfakes. More research into how people, especially children, are using these AI models is essential. OpenAIs work is only a start. Read more from Rhiannon Williams. Bits and Bytes Opinion Why handing over total control to AI agents would be a huge mistake Companies like OpenAI and Butterfly Effect (the startup in China that made Manus) are racing to build AI agents that can do tasks for you by taking over your computer. In this op-ed, some top AI researchers detail the potential missteps that could occur if we cede more control of our digital lives to decision-making AIs. A provocative experiment pitted AI against federal judges Research has long shown that judges are influenced by many factors, like how sympathetic they are to defendants, or when their last meal was. Despite AI models inherent problems with biases and hallucinations, researchers at the University of Chicago Law School wondered if they can present more objective opinions.

AI agents have set the tech industry abuzz. Unlike chatbots, these groundbreaking new systems operate outside of a chat window, navigating multiple applications to execute complex tasks, like scheduling meetings or shopping online, in response to simple user commands. As agents are developed to become more capable, a crucial question emerges: How much control are we willing to surrender, and at what cost? New frameworks and functionalities for AI agents are announced almost weekly, and companies promote the technology as a way to make our lives easier by completing tasks we cant do or dont want to do. Prominent examples include computer use, a function that enables Anthropics Claude system to act directly on your computer screen, and the general AI agent Manus, which can use online tools for a variety of tasks, like scouting out customers or planning trips. These developments mark a major advance in artificial intelligence: systems designed to operate in the digital world without direct human oversight. The promise is compelling. Who doesnt want assistance with cumbersome work or tasks theres no time for? Agent assistance could soon take many different forms, such as reminding you to ask a colleague about their kids basketball tournament or finding images for your next presentation. Within a few weeks, theyll probably be able to make presentations for you. Theres also clear potential for deeply meaningful differences in peoples lives. For people with hand mobility issues or low vision, agents could complete tasks online in response to simple language commands. Agents could also coordinate simultaneous assistance across large groups of people in critical situations, such as by routing traffic to help drivers flee an area en masse as quickly as possible when disaster strikes. But this vision for AI agents brings significant risks that might be overlooked in the rush toward greater autonomy. Our research team at Hugging Face has spent years implementing and investigating these systems, and our recent findings suggest that agent development could be on the cusp of a very serious misstep. Giving up control, bit by bit This core issue lies at the heart of whats most exciting about AI agents: The more autonomous an AI system is, the more we cede human control. AI agents are developed to be flexible, capable of completing a diverse array of tasks that dont have to be directly programmed. For many systems, this flexibility is made possible because theyre built on large language models, which are unpredictable and prone to significant (and sometimes comical) errors. When an LLM generates text in a chat interface, any errors stay confined to that conversation. But when a system can act independently and with access to multiple applications, it may perform actions we didnt intend, such as manipulating files, impersonating users, or making unauthorized transactions. The very feature being soldreduced human oversightis the primary vulnerability. To understand the overall risk-benefit landscape, its useful to characterize AI agent systems on a spectrum of autonomy. The lowest level consists of simple processors that have no impact on program flow, like chatbots that greet you on a company website. The highest level, fully autonomous agents, can write and execute new code without human constraints or oversightthey can take action (moving around files, changing records, communicating in email, etc.) without your asking for anything. Intermediate levels include routers, which decide which human-provided steps to take; tool callers, which run human-written functions using agent-suggested tools; and multistep agents that determine which functions to do when and how. Each represents an incremental removal of human control. Its clear that AI agents can be extraordinarily helpful for what we do every day. But this brings clear privacy, safety, and security concerns. Agents that help bring you up to speed on someone would require that individuals personal information and extensive surveillance over your previous interactions, which could result in serious privacy breaches. Agents that create directions from building plans could be used by malicious actors to gain access to unauthorized areas. And when systems can control multiple information sources simultaneously, potential for harm explodes. For example, an agent with access to both private communications and public platforms could share personal information on social media. That information might not be true, but it would fly under the radar of traditional fact-checking mechanisms and could be amplified with further sharing to create serious reputational damage. We imagine that It wasnt meit was my agent!! will soon be a common refrain to excuse bad outcomes. Keep the human in the loop Historical precedent demonstrates why maintaining human oversight is critical. In 1980, computer systems falsely indicated that over 2,000 Soviet missiles were heading toward North America. This error triggered emergency procedures that brought us perilously close to catastrophe. What averted disaster was human cross-verification between different warning systems. Had decision-making been fully delegated to autonomous systems prioritizing speed over certainty, the outcome might have been catastrophic. Some will counter that the benefits are worth the risks, but wed argue that realizing those benefits doesnt require surrendering complete human control. Instead, the development of AI agents must occur alongside the development of guaranteed human oversight in a way that limits the scope of what AI agents can do. Open-source agent systems are one way to address risks, since these systems allow for greater human oversight of what systems can and cannot do. At Hugging Face were developing smolagents, a framework that provides sandboxed secure environments and allows developers to build agents with transparency at their core so that any independent group can verify whether there is appropriate human control. This approach stands in stark contrast to the prevailing trend toward increasingly complex, opaque AI systems that obscure their decision-making processes behind layers of proprietary technology, making it impossible to guarantee safety. As we navigate the development of increasingly sophisticated AI agents, we must recognize that the most important feature of any technology isnt increasing efficiency but fostering human well-being. This means creating systems that remain tools rather than decision-makers, assistants rather than replacements. Human judgment, with all its imperfections, remains the essential component in ensuring that these systems serve rather than subvert our interests.

OpenAI says over 400 million people use ChatGPT every week. But how does interacting with it affect us? Does it make us more or less lonely? These are some of the questions OpenAI set out to investigate, in partnership with the MIT Media Lab, in a pair of new studies. They found that only a small subset of users engage emotionally with ChatGPT. This isnt surprising given that ChatGPT isnt marketed as an AI companion app like Replika or Character.AI, says Kate Devlin, a professor of AI and society at Kings College London, who did not work on the project. ChatGPT has been set up as a productivity tool, she says. But we know that people are using it like a companion app anyway. In fact, the people who do use it that way are likely to interact with it for extended periods of time, some of them averaging about half an hour a day. The authors are very clear about what the limitations of these studies are, but its exciting to see theyve done this, Devlin says. To have access to this level of data is incredible. The researchers found some intriguing differences between how men and women respond to using ChatGPT. After using the chatbot for four weeks, female study participants were slightly less likely to socialize with people than their male counterparts who did the same. Meanwhile, participants who interacted with ChatGPTs voice mode in a gender that was not their own for their interactions reported significantly higher levels of loneliness and more emotional dependency on the chatbot at the end of the experiment. OpenAI plans to submit both studies to peer-reviewed journals. Chatbots powered by large language models are still a nascent technology, and its difficult to study how they affect us emotionally. A lot of existing research in the areaincluding some of the new work by OpenAI and MITrelies upon self-reported data, which may not always be accurate or reliable. That said, this latest research does chime with what scientists so far have discovered about how emotionally compelling chatbot conversations can be. For example, in 2023 MIT Media Lab researchers found that chatbots tend to mirror the emotional sentiment of a users messages, suggesting a kind of feedback loop where the happier you act, the happier the AI seems, or on the flipside, if you act sadder, so does the AI.OpenAI and the MIT Media Lab used a two-pronged method. First they collected and analyzed real-world data from close to 40 million interactions with ChatGPT. Then they asked the 4,076 users whod had those interactions how they made them feel. Next, the Media Lab recruited almost 1,000 people to take part in a four-week trial. This was more in-depth, examining how participants interacted with ChatGPT for a minimum of five minutes each day. At the end of the experiment, participants completed a questionnaire to measure their perceptions of the chatbot, their subjective feelings of loneliness, their levels of social engagement, their emotional dependence on the bot, and their sense of whether their use of the bot was problematic. They found that participants who trusted and bonded with ChatGPT more were likelier than others to be lonely, and to rely on it more. This work is an important first step toward greater insight into ChatGPTs impact on us, which could help AI platforms enable safer and healthier interactions, says Jason Phang, an OpenAI safety researcher who worked on the project. A lot of what were doing here is preliminary, but were trying to start the conversation with the field about the kinds of things that we can start to measure, and to start thinking about what the long-term impact on users is, he says. Although the research is welcome, its still difficult to identify when a human isand isntengaging with technology on an emotional level, says Devlin. She says the study participants may have been experiencing emotions that werent recorded by the researchers. In terms of what the teams set out to measure, people might not necessarily have been using ChatGPT in an emotional way, but you cant divorce being a human from your interactions [with technology], she says. We use these emotion classifiers that we have created to look for certain thingsbut what that actually means to someones life is really hard to extrapolate." Correction: An earlier version of this article misstated that study participants set the gender of ChatGPT's voice, and that OpenAI did not plan to publish either study. Study participants were assigned the voice mode gender, and OpenAI plans to submit both studies to peer-reviewed journals. The article has since been updated.

The Thwaites glacier is a fortress larger than Florida, a wall of ice that reaches nearly 4,000 feet above the bedrock of West Antarctica, guarding the low-lying ice sheet behind it. But a strong, warm ocean current is weakening its foundations and accelerating its slide into the Amundsen Sea. Scientists fear the waters could topple the walls in the coming decades, kick-starting a runaway process that would crack up the West Antarctic Ice Sheet. That would mark the start of a global climate disaster. The glacier itself holds enough ice to raise ocean levels by more than two feet, which could flood coastlines and force tens of millions of people living in low-lying areas to abandon their homes. The loss of the entire ice sheetwhich could still take centuries to unfoldwould push up sea levels by 11 feet and redraw the contours of the continents. This is why Thwaites is known as the doomsday glacierand why scientists are eager to understand just how likely such a collapse is, when it could happen, and if we have the power to stop it. Scientists at MIT and Dartmouth College founded Arte Glacier Initiative last year in the hope of providing clearer answers to these questions. The nonprofit research organization will officially unveil itself, launch its website, and post requests for research proposals today, March 21, timed to coincide with the UNs inaugural World Day for Glaciers, MIT Technology Review can report exclusively. Arte will also announce it is issuing its first grants, each for around $200,000 over two years, to a pair of glacier researchers at the University of Wisconsin-Madison. One of the organizations main goals is to study the possibility of preventing the loss of giant glaciers, Thwaites in particular, by refreezing them to the bedrock. It would represent a radical intervention into the natural world, requiring a massive, expensive engineering project in a remote, treacherous environment. But the hope is that such a mega-adaptation project could minimize the mass relocation of climate refugees, prevent much of the suffering and violence that would almost certainly accompany it, and help nations preserve trillions of dollars invested in high-rises, roads, homes, ports, and airports around the globe. About a million people are displaced per centimeter of sea-level rise, says Brent Minchew, an associate professor of geophysics at MIT, who cofounded Arte Glacier Initiative and will serve as its chief scientist. If were able to bring that down, even by a few centimeters, then we would safeguard the homes of millions. But some scientists believe the idea is an implausible, wildly expensive distraction, drawing money, expertise, time, and resources away from more essential polar research efforts. Sometimes we can get a little over-optimistic about what engineering can do, says Twila Moon, deputy lead scientist at the National Snow and Ice Data Center at the University of Colorado Boulder. Two possible futures Minchew, who earned his PhD in geophysics at Caltech, says he was drawn to studying glaciers because they are rapidly transforming as the world warms, increasing the dangers of sea-level rise. But over the years, I became less content with simply telling a more dramatic story about how things were going and more open to asking the question of what can we do about it, says Minchew, who will return to Caltech as a professor this summer. Last March, he cofounded Arte Glacier Initiative with Colin Meyer, an assistant professor of engineering at Dartmouth, in the hope of funding and directing research to improve scientific understanding of two big questions: How big a risk does sea-level rise pose in the coming decades, and can we minimize that risk? Brent Minchew, an MIT professor of geophysics, co-founded Arte Glacier Initiative and will serve as its chief scientist.COURTESY: BRENT MINCHEW Philanthropic funding is needed to address both of these challenges, because theres no private-sector funding for this kind of research and government funding is minuscule, says Mike Schroepfer, the former Meta chief technology officer turned climate philanthropist, who provided funding to Arte through his new organization, Outlier Projects. The nonprofit has now raised about $5 million from Outlier and other donors, including the Navigation Fund, the Kissick Family Foundation, the Sky Foundation, the Wedner Family Foundation, and the Grantham Foundation. Minchew says they named the organization Arte, mainly because its the sharp mountain ridge between two valleys, generally left behind when a glacier carves out the cirques on either side. It directs the movement of the glacier and is shaped by it. Its meant to symbolize two possible futures, he says. One where we do something; one where we do nothing. Improving forecasts The somewhat reassuring news is that, even with rising global temperatures, it may still take thousands of years for the West Antarctic Ice Sheet to completely melt. In addition, sea-level rise forecasts for this century generally range from as little as 0.28 meters (11 inches) to 1.10 meters (about three and a half feet), according to the latest UN climate panel report. The latter only occurs under a scenario with very high greenhouse gas emissions (SSP5-8.5), which significantly exceeds the pathway the world is now on. But theres still a low-likelihood that ocean levels could surge nearly two meters (about six and a half feet) by 2100 that cannot be excluded, given deep uncertainty linked to ice-sheet processes, the report adds. Two meters of sea-level rise could force nearly 190 million people to migrate away from the coasts, unless regions build dikes or other shoreline protections, according to some models. Many more people, mainly in the tropics, would face heightened flooding dangers. Much of the uncertainty over what will happen this century comes down to scientists' limited understanding of how Antarctic ice sheets will respond to growing climate pressures. The initial goal of Arte Glacier Initiative is to help narrow the forecast ranges by improving our grasp of how Thwaites and other glaciers move, melt, and break apart. Gravity is the driving force nudging glaciers along the bedrock and reshaping them as they flow. But many of the variables that determine how fast they slide lie at the base. That includes the type of sediment the river of ice slides along; the size of the boulders and outcroppings it contorts around; and the warmth and strength of the ocean waters that lap at its face. In addition, heat rising from deep in the earth warms the ice closest to the ground, creating a lubricating layer of water that hastens the glaciers slide. That acceleration, in turn, generates more frictional heat that melts still more of the ice, creating a self-reinforcing feedback effect. Minchew and Meyer are confident that the glaciology field is at a point where it could speed up progress in sea-level rise forecasting, thanks largely to improving observational tools that are producing more and better data. That includes a new generation of satellites orbiting the planet that can track the shifting shape of ice at the poles at far higher resolutions than in the recent past. Computer simulations of ice sheets, glaciers and sea ice are improving as well, thanks to growing computational resources and advancing machine learning techniques. On March 21, Arte will issue a request for proposals from research teams to contribute to an effort to collect, organize, and openly publish existing observational glacier data. Much of that expensively gathered information is currently inaccessible to researchers around the world, Minchew says. Colin Meyer, an assistant professor of engineering at Dartmouth, co-founded Arte Glacier Initiative.ELI BURAK By funding teams working across these areas, Artes founders hope to help produce more refined ice-sheet models and narrower projections of sea-level rise. This improved understanding would help cities plan where to build new bridges, buildings, and homes, and to determine whether theyll need to erect higher seawalls or raise their roads, Meyer says. It could also provide communities with more advance notice of the coming dangers, allowing them to relocate people and infrastructure to safer places through an organized process known as managed retreat. A radical intervention But the improved forecasts might also tell us that Thwaites is closer to tumbling into the ocean than we think, underscoring the importance of considering more drastic measures. One idea is to build berms or artificial islands to prop up fragile parts of glaciers, and to block the warm waters that rise from the deep ocean and melt them from below. Some researchers have also considered erecting giant, flexible curtains anchored to the seabed to achieve the latter effect. Others have looked at scattering highly reflective beads or other materials across ice sheets, or pumping ocean water onto them in the hopes it would freeze during the winter and reinforce the headwalls of the glaciers. But the concept of refreezing glaciers in place, know as a basal intervention, is gaining traction in scientific circles, in part because theres a natural analogue for it. The glacier that stalled About 200 years ago, the Kamb Ice Stream, another glacier in West Antarctica that had been sliding about 350 meters (1,150 feet) per year, suddenly stalled. Glaciologists believe an adjacent ice stream intersected with the catchment area under the glacier, providing a path for the water running below it to flow out along the edge instead. That loss of fluid likely slowed down the Kamb Ice Stream, reduced the heat produced through friction, and allowed water at the surface to refreeze. The deceleration of the glacier sparked the idea that humans might be able to bring about that same phenomenon deliberately, perhaps by drilling a series of boreholes down to the bedrock and pumping up water from the bottom. Minchew himself has focused on a variation he believes could avoid much of the power use and heavy operating machinery hassles of that approach: slipping long tubular devices, known as thermosyphons, down nearly to the bottom of the boreholes. These passive heat exchangers, which are powered only by the temperature differential between two areas, are commonly used to keep permafrost cold around homes, buildings and pipelines in Arctic regions. The hope is that we could deploy extremely long ones, stretching up to two kilometers and encased in steel pipe, to draw warm temperatures away from the bottom of the glacier, allowing the water below to freeze. Minchew says hes in the process of producing refined calculations, but estimates that halting Thwaites could require drilling as many as 10,000 boreholes over a 100-square-kilometer area. He readily acknowledges that would be a huge undertaking, but provides two points of comparison to put such a project into context: Melting the necessary ice to create those holes would require roughly the amount of energy all US domestic flights consume from jet fuel in about two and a half hours. Or, it would produce about the same level of greenhouse gas emissions as constructing 10 kilometers of seawalls, a small fraction of the length the world would need to build if it cant slow down the collapse of the ice sheets, he says. "Kick the system" One of Artes initial grantees is Marianne Haseloff, an assistant professor of geoscience at the University of Wisconsin-Madison. She studies the physical processes that govern the behavior of glaciers and is striving to more faithfully represent them in ice sheet models. Haseloff says she will use those funds to develop mathematical methods that could more accurately determine whats known as basal shear stress, or the resistance of the bed to sliding glaciers, based on satellite observations. That could help refine forecasts of how rapidly glaciers will slide into the ocean, in varying settings and climate conditions. Artes other initial grant will go to Lucas Zoet, an associate professor in the same department as Haseloff and the principal investigator with the Surface Processes group. He intends to use the funds to build the labs second ring shear device, the technical term for a simulated glacier. The existing device, which is the only one operating in the world, stands about eight feet tall and fills the better part of a walk-in freezer on campus. The core of the machine is a transparent drum filled with a ring of ice, sitting under pressure and atop a layer of sediment. It slowly spins for weeks at a time as sensors and cameras capture how the ice and earth move and deform. Lucas Zoet, an associate professor at the University of WisconsinMadison, stands in front of his lab's ring shear device, a simulated glacier.ETHAN PARRISH The research team can select the sediment, topography, water pressure, temperature, and other conditions to match the environment of a real-world glacier of interest, be it Thwaites todayor Thwaites in 2100, under a high greenhouse gas emissions scenario. Zoet says these experiments promise to improve our understanding of how glaciers move over different types of beds, and to refine an equation known as the slip law, which represents these glacier dynamics mathematically in computer models. The second machine will enable them to run more experiments and to conduct a specific kind that the current device cant: a scaled-down, controlled version of the basal intervention. Zoet says the team will be able to drill tiny holes through the ice, then pump out water or transfer heat away from the bed. They can then observe whether the simulated glacier freezes to the base at those points and experiment with how many interventions, across how much space, are required to slow down its movement. It offers a way to test out different varieties of the basal intervention that is far easier and cheaper than using water drills to bore to the bottom of an actual glacier in Antarctica, Zoet says. The funding will allow the lab to explore a wide range of experiments, enabling them to kick the system in a way we wouldnt have before, he adds. Virtually impossible The concept of glacier interventions is in its infancy. There are still considerable unknowns and uncertainties, including how much it would cost, how arduous the undertaking would be, and which approach would be most likely to work, or if any of them are feasible. This is mostly a theoretical idea at this point, says Katharine Ricke, an associate professor at the University of California, San Diego, who researches the international relations implications of geoengineering, among other topics. Conducting extensive field trials or moving forward with full-scale interventions may also require surmounting complex legal questions, she says. Antarctica isnt owned by any nation, but its the subject of competing territorial claims among a number of countries and governed under a decades-old treaty to which dozens are a party. The basal interventionrefreezing the glacier to its bedfaces numerous technical hurdles that would make it virtually impossible to execute, Moon and dozens of other researchers argued in a recent preprint paper, Safeguarding the polar regions from dangerous geoengineering. Among other critiques, they stress that subglacial water systems are complex, dynamic, and interconnected, making it highly difficult to precisely identify and drill down to all the points that would be necessary to remove enough water or add enough heat to substantially slow down a massive glacier. Further, they argue that the interventions could harm polar ecosystems by adding contaminants, producing greenhouse gases, or altering the structure of the ice in ways that may even increase sea-level rise. Overwhelmingly, glacial and polar geoengineering ideas do not make sense to pursue, in terms of the finances, the governance challenges, the impacts, and the possibility of making matters worse, Moon says. No easy path forward But Douglas MacAyeal, professor emeritus of glaciology at the University of Chicago, says the basal intervention would have the lightest environmental impact among the competing ideas. He adds that nature has already provided an example of it working, and that much of the needed drilling and pumping technology is already in use in the oil industry. I would say its the strongest approach at the starting gate, he says, but we dont really know anything about it yet. The research still has to be done. Its very cutting-edge. Minchew readily acknowledges that there are big challenges and significant unknownsand that some of these ideas may not work. But he says its well worth the effort to study the possibilities, in part because much of the research will also improve our understanding of glacier dynamics and the risks of sea-level riseand in part because its only a question of when, not if, Thwaites will collapse. Even if the world somehow halted all greenhouse gas emissions tomorrow, the forces melting that fortress of ice will continue to do so. So one way or another, the world will eventually need to make big, expensive, difficult interventions to protect people and infrastructure. The cost and effort of doing one project in Antarctica, he says, would be small compared to the global effort required to erect thousands of miles of seawalls, ratchet up homes, buildings, and roads, and relocate hundreds of millions of people. One thing is challengingand the other is even more challenging, Minchew says. Theres no easy path forward.

Over the past couple of weeks, Ive been following news of the deaths of actor Gene Hackman and his wife, pianist Betsy Arakawa. It was heartbreaking to hear how Arakawa appeared to have died from a rare infection days before her husband, who had advanced Alzheimers disease and may have struggled to understand what had happened. But as I watched the medical examiner reveal details of the couples health, I couldnt help feeling a little uncomfortable. Media reports claim that the couple liked their privacy and had been out of the spotlight for decades. But here I was, on the other side of the Atlantic Ocean, being told what pills Arakawa had in her medicine cabinet, and that Hackman had undergone multiple surgeries. It made me wonder: Should autopsy reports be kept private? A persons cause of death is public information. But what about other intimate health details that might be revealed in a postmortem examination? The processes and regulations surrounding autopsies vary by country, so well focus on the US, where Hackman and Arakawa died. Here, a medico-legal autopsy may be organized by law enforcement agencies and handled through courts, while a clinical autopsy may be carried out at the request of family members. And there are different levels of autopsysome might involve examining specific organs or tissues, while more thorough examinations would involve looking at every organ and studying tissues in the lab. The goal of an autopsy is to discover the cause of a persons death. Autopsy reports, especially those resulting from detailed investigations, often reveal health conditionsconditions that might have been kept private while the person was alive. There are multiple federal and state laws designed to protect individuals health information. For example, the Health Insurance Portability and Accountability Act (HIPAA) protects individually identifiable health information up to 50 years after a persons death. But some things change when a person dies. For a start, the cause of death will end up on the death certificate. That is public information. The public nature of causes of death is taken for granted these days, says Lauren Solberg, a bioethicist at the University of Florida College of Medicine. It has become a public health statistic. She and her student Brooke Ortiz, who have been researching this topic, are more concerned about other aspects of autopsy results. The thing is, autopsies can sometimes reveal more than what a person died from. They can also pick up what are known as incidental findings. An examiner might find that a person who died following a covid-19 infection also had another condition. Perhaps that condition was undiagnosed. Maybe it was asymptomatic. That finding wouldnt appear on a death certificate. So who should have access to it? The laws over who should have access to a persons autopsy report vary by state, and even between counties within a state. Clinical autopsy results will always be made available to family members, but local laws dictate which family members have access, says Ortiz. Genetic testing further complicates things. Sometimes the people performing autopsies will run genetic tests to help confirm the cause of death. These tests might reveal what the person died from. But they might also flag genetic factors unrelated to the cause of death that might increase the risk of other diseases. In those cases, the persons family members might stand to benefit from accessing that information. My health information is my health informationuntil it comes to my genetic health information, says Solberg. Genes are shared by relatives. Should they have the opportunity to learn about potential risks to their own health? This is where things get really complicated. Ethically speaking, we should consider the wishes of the deceased. Would that person have wanted to share this information with relatives? Its also worth bearing in mind that a genetic risk factor is often just that; theres often no way to know whether a person will develop a disease, or how severe the symptoms would be. And if the genetic risk is for a disease that has no treatment or cure, will telling the persons relatives just cause them a lot of stress? One 27-year-old experienced this when a 23&Me genetic test told her she had a 28% chance of developing late-onset Alzheimers disease by age 75 and a 60% chance by age 85. Im suddenly overwhelmed by this information, she posted on a dementia forum. I cant help feeling this overwhelming sense of dread and sadness that Ill never be able to un-know this information. In their research, Solberg and Ortiz came across cases in which individuals who had died in motor vehicle accidents underwent autopsies that revealed other, asymptomatic conditions. One man in his 40s who died in such an accident was found to have a genetic kidney disease. A 23-year-old was found to have had kidney cancer. Ideally, both medical teams and family members should know ahead of time what a person would have wantedwhether thats an autopsy, genetic testing, or health privacy. Advance directives allow people to clarify their wishes for end-of-life care. But only around a third of people in the US have completed one. And they tend to focus on care before death, not after. Solberg and Ortiz think they should be expanded. An advance directive could specify how people want to share their health information after theyve died. Talking about death is difficult, says Solberg. For physicians, for patients, for familiesit can be uncomfortable. But it is important. On March 17, a New Mexico judge granted a request from a representative of Hackmans estate to seal police photos and bodycam footage as well as the medical records of Hackman and Arakawa. The medical investigator is temporarily restrained from disclosing the Autopsy Reports and/or Death Investigation Reports for Mr. and Mrs. Hackman, according to Deadline.

Europe is on the cusp of a new dawn in commercial space technology. As global political tensions intensify and relationships with the US become increasingly strained, several European companies are now planning to conduct their own launches in an attempt to reduce the continents reliance on American rockets. In the coming days, Isar Aerospace, a company based in Munich, will try to launch its Spectrum rocket from a site in the frozen reaches of Andya island in Norway. A spaceport has been built there to support small commercial rockets, and Spectrum is the first to make an attempt. Its a big milestone, says Jonathan McDowell, an astronomer and spaceflight expert at the Harvard-Smithsonian Center for Astrophysics in Massachusetts. Its long past time for Europe to have a proper commercial launch industry. Spectrum stands 28 meters (92 feet) tall, the length of a basketball court. The rocket has two stages, or parts, the first with nine enginespowered by an unusual fuel combination of liquid oxygen and propane not seen on other rockets before, which Isar says results in higher performanceand the second with a single engine to give satellites their final kick into orbit. The ultimate goal for Spectrum is to carry satellites weighing up to 1,000 kilograms (2,200 pounds) to low Earth orbit. On this first launch, however, there are no satellites on board, because success is anything but guaranteed. Its unlikely to make it to orbit, says Malcolm Macdonald, an expert in space technology at Strathclyde University in Scotland. The first launch of any rocket tends not to work. Regardless of whether it succeeds or fails, the launch attempt heralds an important moment as Europe tries to kick-start its own private rocket industry. Two other companiesOrbex of the UK and Rocket Factory Augsburg (RFA) of Germanyare expected to make launch attempts later this year. These efforts could give Europe multiple ways to reach space without having to rely on US rockets. Europe has to be prepared for a more uncertain future, says Macdonald. The uncertainty of what will happen over the next four years with the current US administration amplifies the situation for European launch companies. Trailing in the USs wake Europe has for years trailed behind the US in commercial space efforts. The successful launch of SpaceXs first rocket, the Falcon 1, in 2008 began a period of American dominance of the global launch market. In 2024, 145 of 263 global launch attempts were made by US entitiesand SpaceX accounted for 138 of those. SpaceX is the benchmark at the moment, says Jonas Kellner, head of marketing, communications, and political affairs at RFA. Other US companies, like Rocket Lab (which launches from both the US and New Zealand), have also become successful, while commercial rockets are ramping up in China, too. Europe has launched its own government-funded Ariane and Vega rockets for decades from the Guiana Space Centre, a spaceport it operates in French Guiana in South America. Most recently, on March 6, the European Space Agency (ESA) launched its new heavy-lift Ariane 6 rocket from there for the first time. However, the history of rocket launches from Europe itself is much more limited. In 1997 the US defense contractor Northrop Grumman air-launched a Pegasus rocket from a plane that took off from the Canary Islands. In 2023 the US company Virgin Orbit failed to reach orbit with its LauncherOne rocket after a launch attempt from Cornwall in the UK. No vertical orbital rocket launch has ever been attempted from Western Europe. Isar Aerospace is one of a handful of companies hoping to change that with help from agencies like ESA, which has provided funding to rocket launch companies through its Boost program since 2019. In 2024 it awarded 44.22 million ($48 million) to Isar, Orbex, RFA, and the German launch company HyImpulse. The hope is that one or more of the companies will soon begin regular launches from Europe from two potential sites: Isars chosen location in Andya and the SaxaVord Spaceport on the Shetland Islands north of the UK, where RFA and Orbex plan to make their attempts. I expect four or five companies to get to the point of launching, and then over a period of years reliability and launch cadence [or frequency] will determine which one or two of them survives, says McDowell. ISAR AEROSPACE Unique advantages In their initial form these rockets will not rival anything on offer from SpaceX in terms of size and cadence. SpaceX sometimes launches its 70-meter (230-foot) Falcon 9 rocket multiple times per week and is developing its much larger Starship vehicle for missions to the moon and Mars. However, the smaller European rockets can allow companies in Europe to launch satellites to orbit without having to travel all the way across the Atlantic. There is an advantage to having it closer, says Kellner, who says it will take RFA one or two days by sea to get its rockets to SaxaVord, versus one or two weeks to travel across the Atlantic. Launching from Europe is useful, too, for reaching specific orbits. Traditionally, a lot of satellite launches have taken place near the equator, in places such as Cape Canaveral in Florida, to get an extra boost from Earths rotation. Crewed spacecraft have also launched from these locations to reach space stations in equatorial orbit around Earth and the moon. From Europe, though, satellites can launch north over uninhabited stretches of water to reach polar orbit, which can allow imaging satellites to see the entirety of Earth rotate underneath them. Increasingly, says McDowell, companies want to place satellites into sun-synchronous orbit, a type of polar orbit where a satellite orbiting Earth stays in perpetual sunlight. This is useful for solar-powered vehicles. By far the bulk of the commercial market now is sun-synchronous polar orbit, says McDowell. So having a high-latitude launch site that has good transport links with customers in Europe does make a difference. Europes end goal In the longer term, Europes rocket ambitions might grow to vehicles that are more of a match for the Falcon 9 through initiatives like ESAs European Launcher Challenge, which will award contracts later this year. We are hoping to develop [a larger vehicle] in the European Launcher Challenge, says Kellner. Perhaps Europe might even consider launching humans into space one day on larger rockets, says Thilo Kranz, ESAs program manager for commercial space transportation. We are looking into this, he says. If a commercial operator comes forward with a smart way of approaching [crewed] access to space, that would be a favorable development for Europe. A separate ESA project called Themis, meanwhile, is developing technologies to reuse rockets. This was the key innovation of SpaceXs Falcon 9, allowing the company to dramatically drive down launch costs. Some European companies, like MaiaSpace and RFA, are also investigating reusability. The latter is planning to use parachutes to bring the first stage of its rocket back to a landing in the sea, where it can be recovered. As soon as you get up to something like a Falcon 9 competitor, I think its clear now that reusability is crucial, says McDowell. Theyre not going to be economically competitive without reusability. The end goal for Europe is to have a sovereign rocket industry that reduces its reliance on the US. Where we are in the broader geopolitical situation probably makes this a bigger point than it might have been six months ago, says Macdonald. The continent has already shown it can diversify from the US in other ways. Europe now operates its own successful satellite-based alternative to the US Global Positioning System (GPS), called Galileo; it began launching in 2011 and is four times more accurate than its American counterpart. Isar Aerospace, and the companies that follow, might be the first sign that commercial European rockets can break from America in a similar way. We need to secure access to space, says Kranz, and the more options we have in launching into space, the higher the flexibility.

At a conference dedicated to energy technology that I attended this week, I noticed an outward attitude of optimism and excitement. But its hard to miss the current of uncertainty just underneath. The ARPA-E Energy Innovation Summit, held this year just outside Washington, DC, gathers some of the most cutting-edge innovators working on everything from next-generation batteries to plants that can mine for metals. Researchers whose projects have received funding from ARPA-Epart of the US Department of Energy that gives money to high-risk research in energygather to show their results and mingle with each other, investors, and nosy journalists like yours truly. (For more on a few of the coolest things I saw, check out this story.) This year, though, there was an elephant in the room, and its the current state of the US federal government. Or maybe its climate change? In any case, the vibes were weird. The last time I was at this conference, two years ago, climate change was a constant refrain on stage and in conversations. The central question was undoubtedly: How do we decarbonize, generate energy, and run our lives without relying on polluting fossil fuels? This time around, I didnt hear the phrase climate change once during the opening session, including in speeches from US Secretary of Energy Chris Wright and acting ARPA-E Director Daniel Cunningham. The focus was on American energy dominance, on how we can get our hands on more, more, more energy to meet growing demand. Last week, Wright spoke at an energy conference in Houston and had a lot to say about climate, calling climate change a side effect of building the modern world and climate policies irrational and quasi-religious, and he said that when it came to climate action, the cure had become worse than the disease. I was anticipating similar talking points at the summit, but this week, climate change hardly got a mention. What I noticed in Wrights speech and in the choice of programming throughout the conference is that some technologies appear to be among the favored, and others are decidedly less prominent. Nuclear power and fusion were definitely on the in list. There was a nuclear panel in the opening session, and in his remarks Wright called out companies like Commonwealth Fusion Systems and Zap Energy. He also praised small modular reactors. Renewables, including wind and solar, were mentioned only in the context of their inconsistencyWright dwelled on that, rather than on other facts Id argue are just as important, like that they are among the cheapest methods of generating electricity today. In any case, Wright seemed appropriately hyped about energy, given his role in the administration. Call me biased, but I think theres no more impactful place to work in than energy, Wright said during his opening remarks on the first morning of the summit. He sang the praises of energy innovation, calling it a tool to drive progress, and outlined his long career in the field. This all comes after a chaotic couple of months for the federal government that are undoubtedly affecting the industry. Mass layoffs have hit federal agencies, including the Department of Energy. President Donald Trump very quickly tried to freeze spending from the Inflation Reduction Act, which includes tax credits and other support for EVs and power plants. As I walked around the showcase and chatted with experts over coffee, I heard a range of reactions to the opening session and feelings about this moment for the energy sector. People working in industries the Trump administration seems to favor, like nuclear energy, tended to be more positive. Some in academia who rely on federal grants to fund their work were particularly nervous about what comes next. One researcher refused to talk to me when I said I was a journalist. In response to my questions about why they werent able to discuss the technology on display at their booth, another member on the same project said only that its a wild time. Making progress on energy technology doesnt require that we all agree on exactly why were doing it. But in a moment when we need all the low-carbon technologies we can get to address climate changea problem scientists overwhelmingly agree is a threat to our planetI find it frustrating that politics can create such a chilling effect in some sectors. At the conference, I listened to smart researchers talk about their work. I saw fascinating products and demonstrations, and Im still optimistic about where energy can go. But I also worry that uncertainty about the future of research and government support for emerging technologies will leave some valuable innovations in the dust.

Where can you find lasers, electric guitars, and racks full of novel batteries, all in the same giant room? This week, the answer was the 2025 ARPA-E Energy Innovation Summit just outside Washington, DC. Energy innovation can take many forms, and the variety in energy research was on display at the summit. ARPA-E, part of the US Department of Energy, provides funding for high-risk, high-reward research projects. The summit gathers projects the agency has funded, along with investors, policymakers, and journalists. Hundreds of projects were exhibited in a massive hall during the conference, featuring demonstrations and research results. Here are four of the most interesting innovations MIT Technology Review spotted on site. Steel made with lasers Startup Limelight Steel has developed a process to make iron, the main component in steel, by using lasers to heat iron ore to super-high temperatures. Steel production makes up roughly 8% of global greenhouse gas emissions today, in part because most steel is still made with blast furnaces, which rely on coal to hit the high temperatures that kick off the required chemical reactions. Limelight instead shines lasers on iron ore, heating it to temperatures over 1,600 C. Molten iron can then be separated from impurities, and the iron can be put through existing processes to make steel. The company has built a small demonstration system with a laser power of about 1.5 kilowatts, which can process between 10 and 20 grams of ore. The whole system is made up of 16 laser arrays, each just a bit larger than a postage stamp. The components in the demonstration system are commercially available; this particular type of laser is used in projectors. The startup has benefited from years of progress in the telecommunications industry that has helped bring down the cost of lasers, says Andy Zhao, the companys cofounder and CTO. The next step is to build a larger-scale system that will use 150 kilowatts of laser power and could make up to 100 tons of steel over the course of a year. Rocks that can make fuel The hunks of rock at a booth hosted by MIT might not seem all that high-tech, but someday they could help produce fuels and chemicals. A major topic of conversation at the ARPA-E summit was geologic hydrogentheres a ton of excitement about efforts to find underground deposits of the gas, which can be used as a fuel across a wide range of industries, including transportation and heavy industry. Last year, ARPA-E funded a handful of projects on the topic, including one in Iwnetim Abates lab at MIT. Abate is among the researchers who are aiming not just to hunt for hydrogen, but to actually use underground conditions to help produce it. Earlier this year, his team published research showing that by using catalysts and conditions common in the subsurface, scientists can produce hydrogen as well as other chemicals, like ammonia. Abate cofounded a spinout company, Addis Energy, to commercialize the research, which has since also received ARPA-E funding. All the rocks on the table, from the chunk of dark, hard basalt to the softer talc, could be used to produce these chemicals. An electric guitar powered by iron nitride magnets The sound of music drifted from the Niron Magnetics booth across nearby walkways. People wandering by stopped to take turns testing out the companys magnets, in the form of an electric guitar. Most high-powered magnets today contain neodymiumdemand for them is set to skyrocket in the coming years, especially as the world builds more electric vehicles and wind turbines. Supplies could stretch thin, and the geopolitics are complicated because most of the supply comes from China. Niron is making new magnets that dont contain rare earth metals. Instead, Nirons technology is based on more abundant materials: nitrogen and iron. The guitar is a demonstration producttoday, magnets in electric guitars typically contain aluminum, nickel, and cobalt-based magnets that help translate the vibrations from steel strings into an electric signal that is broadcast through an amplifier. Niron made an instrument using its iron nitride magnets instead. (See photos of the guitar from an event last year here.) Niron opened a pilot commercial facility in late 2024 that has the capacity to produce 10 tons of magnets annually. Since we last covered Niron, in early 2024, the company has announced plans for a full-scale plant, which will have an annual capacity of about 1,500 tons of magnets once its fully ramped up. Batteries for powering high-performance data centers The increasing power demand from AI and data centers was another hot topic at the summit, with server racks dotting the showcase floor to demonstrate technologies aimed at the sector. One stuffed with batteries caught my eye, courtesy of Natron Energy. The company is making sodium-ion batteries to help meet power demand from data centers. Data centers energy demands can be incredibly variableand as their total power needs get bigger, those swings can start to affect the grid. Natrons sodium-ion batteries can be installed at these facilities to help level off the biggest peaks, allowing computing equipment to run full out without overly taxing the grid, says Natron cofounder and CTO Colin Wessells. Sodium-ion batteries are a cheaper alternative to lithium-based chemistries. Theyre also made without lithium, cobalt, and nickel, materials that are constrained in production or processing. Were seeing some varieties of sodium-ion batteries popping up in electric vehicles in China. Natron opened a production line in Michigan last year, and the company plans to open a $1.4 billion factory in North Carolina.

DOWNLOAD THE REPORT But despite this promise, industry adoption still lags. Data-sharing remains limited and companies across the value chain have vastly different needs and capabilities. There are also few standards and data governance protocols in place, and more talent and skills are needed to keep pace with the technological wave. All the same, progress is being made and the potential for AI in the food sector is huge. Key findings from the report are as follows: Predictive analytics are accelerating R&D cycles in crop and food science. AI reduces the time and resources needed to experiment with new food productsand turns traditional trial-and-error cycles into more efficient data-driven discoveries. Advanced models and simulations enable scientists to explore natural ingredients and processes by simulating thousands of conditions, configurations, and genetic variations until they crack the right combination. AI is bringing data-driven insights to a fragmented supply chain. AI can revolutionize the food industrys complex value chain by breaking operational silos and translating vast streams of data into actionable intelligence. Notably, large language models (LLMs) and chatbots can serve as digital interpreters, democratizing access to data analysis for farmers and growers, and enabling more informed, strategic decisions by food companies.Partnerships are crucial for maximizing respective strengths. While large agricultural companies lead inAI implementation, promising breakthroughs often emerge from strategic collaborations that leverage complementary strengths with academic institutions and startups. Large companies contribute extensive datasets and industry experience, while startups bring innovation, creativity, and a clean data slate. Combining expertise in a collaborative approach can increase the uptake of AI. Download the full report. This content was produced by Insights, the custom content arm of MIT Technology Review.

This is today's edition ofThe Download,our weekday newsletter that provides a daily dose of what's going on in the world of technology. HIV could infect 1,400 infants every day because of US aid disruptions Around 1,400 infants are being infected by HIV every day as a result of the new US administrations cuts to funding to AIDS organizations, new modeling suggests. In an executive order issued January 20, President Donald Trump paused new foreign aid funding to global health programs.

Around 1,400 infants are being infected by HIV every day as a result of the new US administrations cuts to funding to AIDS organizations, new modeling suggests. In an executive order issued January 20, President Donald Trump paused new foreign aid funding to global health programs, and four days later, US Secretary of State Marco Rubio issued a stop-work order on existing foreign aid assistance. Surveys suggest that these changes forced more than a third of global organizations that provide essential HIV services to close within days of the announcements. Hundreds of thousands of people are losing access to HIV treatments as a result. Women and girls are missing out on cervical cancer screening and services for gender-based violence, too. A waiver Rubio later issued in an attempt to restore lifesaving services has had very little impact. We are in a crisis, said Jennifer Sherwood, director of research, public policy, at amfAR, the Foundation for AIDS Research, at a data-sharing event on March 17 at Columbia University in New York. Even funds that had already been appropriated, that were in the field, in peoples bank accounts, [were] frozen. Rubio approved a waiver for life-saving humanitarian assistance on January 28. This resumption is temporary in nature, and with limited exceptions as needed to continue life-saving humanitarian assistance programs, no new contracts shall be entered into, he said in a statement at the time. The US Presidents Emergency Plan for AIDS Relief (PEPFAR), which invests millions of dollars in the global AIDS response every year, was also granted a waiver February 1 to continue life-saving work. Despite this waiver, there have been devastating reports of the impact on health programs across the many low-income countries that relied on the US Agency for International Development (USAID), which oversees PEPFAR, for funding. To get a better sense of the overall impact, amfAR conducted two surveys looking at more than 150 organizations that rely on PEPFAR funding in more than 26 countries. We found really severe disruptions to HIV services, said Sherwood, who presented the findings at Columbia. About 90% of our participants said [the cuts] had severely limited their ability to deliver HIV services. Specifically, 94% of follow-up services designed to monitor peoples progress were either canceled or disrupted. There were similarly dramatic disruptions to services for HIV testing, treatment, and prevention, and 92% of services for gender-based violence were canceled or disrupted. The cuts have plunged organizations into a deep financial crisis, said Sherwood. Almost two-thirds of respondents said community-based staff were laid off before the end of January. When the team asked these organizations how long they could stay open without US funding, 36% said they had already closed. Only 14% said that they were able to stay open longer than a month, said Sherwood. And this data was collected longer than a month ago. The organizations said tens of thousands of the people they serve would lose HIV treatment within a month. For some organizations, that figure was over 100,000, said Sherwood. Part of the problem is that the stop-work order came at a time when these organizations were already experiencing shortages in commodities, Sherwood said. Typically, centers might give a person a six-month supply of antiretroviral drugs. Before the stop-work order, many organizations were only giving one-month supplies. Almost all of their clients are due to come back and pick up [more] treatments in this 90-day freeze, she said. You can really see the panic this has caused. The waiver for life-saving treatment didnt do much to remedy this situation. Only 5% of the organizations received funds under the waiver, while the vast majority either were told they didnt qualify or had not been told they could restart services. While the waiver might be one important avenue to restart some services, it cannot, on the whole, save the US HIV program, says Sherwood. It is very limited in scope, and it has not been widely communicated to the field. AmfAR isnt the only organization tracking the impact of US funding cuts. At the same event, Sara Casey, assistant professor of population and family health at Columbia, presented results of a survey of 101 people who work in organizations reliant on US aid. They reported seeing disruptions to services in humanitarian responses, gender-based violence, mental health, infectious diseases, essential medicines and vaccines, and more. Many of these should have been eligible for the life-saving waivers, Casey said. Casey and her colleagues have also been interviewing people in Colombia, Kenya, and Nepal. In those countries, women of reproductive age, newborns and children, people living with HIV, members of the LGBTQI+ community, and migrants are among those most affected by the cuts, she said, and health workers, who are primarily women, are losing their livelihoods. There will be really disproportionate impacts on the worlds most vulnerable, said Sherwood. Women make up 67% of the health-care workforce, according to the World Health Organization. They also make up 63% of PEPFAR clients. PEPFAR has supported gender equality and services for gender-based violence. We dont know if other countries or other donors can or will pick up these types of programs, especially in the face of competing priorities about keeping people on treatment and keeping people alive, said Sherwood. Sherwood and her colleagues at amfAR have also done some modeling work to determine the potential impact of cuts to PEPFAR on women and girls, using data from last year to create their estimates. Each day that the stop-work order is in place, we estimate that there are 1,400 new HIV infections among infants, she said. And every day, over 7,000 women stand to miss out on cervical cancer screenings. The funding cuts have also had a dramatic effect on mental-health services, said Farah Arabe, who serves on the advisory board of the Global Mental Health Action Network. Arabe presented the preliminary findings of an ongoing survey of mental-health organizations from 29 countries that receive US aid. Unfortunately, this is a very grim picture, she said. Only 5% of individuals who were receiving services in 2024 will be able to receive services in 2025. The same goes for children and adolescents. This is a particularly sad picture because children are going through brain development, she said. Impacts at this early stage of life have lifelong impacts on academic achievement, economic productivity, mental health, physical health even the ability to parent the next generation. For now, nonprofits and aid and research organizations are scrambling to try to understand, and potentially limit, the impact of the cuts. Some are hoping to locate new sources of funding, independent of the US. I am deeply concerned that progress in disease eradication, poverty reduction, and gender equality is at risk of being reversed, said Thoai Ngo of Columbia Universitys Mailman School of Public Health, who chaired the event. Without urgent action, preventable deaths will rise, more people will fall into poverty, and as always, women and girls will bear the heaviest burden. On March 10, Rubio announced the results of his departments review of USAID. After a 6 week review we are officially cancelling 83% of the programs at USAID, he shared via the social media platform X.

When you might start speaking to robots Last week, Google made a somewhat surprising announcement. It launched a version of its AI model, Gemini, that can do things not just in the digital realm of chatbots and internet search but out here in the physical world, via robots. Gemini Robotics fuses the power of large language models with spatial reasoning, allowing you to tell a robotic arm to do something like put the grapes in the clear glass bowl. These verbal commands get filtered by the LLM, which identifies intentions from what youre saying and then breaks them down into commands that the robot can carry out. You might be wondering if this means your home or workplace might one day be filled with robots you can bark orders at.

Job titles of the future: Pharmaceutical-grade mushroom grower Studies have indicated that psychedelic drugs, such as psilocybin and MDMA, have swift-acting and enduring antidepressant effects. Though the US Food and Drug Administration denied the first application for medical treatments involving psychedelics (an MDMA-based therapy) last August, these drugs appear to be on the road to mainstream medicine. Research into psilocybin has been slowed in part by the complexity of the trials, but the data already shows promise for the psychedelic compound within so-called magic mushrooms. Eventually, the FDA will decide whether to approve it to treat depression. If and when it doesa move that would open up a vast legal medical marketwho will grow the mushrooms?

In the ever-evolving world of health care, the role of technology is becoming increasingly crucial. From improving patient outcomes to streamlining administrative processes, digital technologies are changing the face of the industry. However, for startups developing health tech solutions, breaking into the market and scaling their products can be a challenging journey, requiring access to resources, expertise, and a network they might not have. This is where health tech accelerator programs come in. Health tech accelerator programs are designed to support early-stage startups in the health technology space, providing them with the resources, mentorship, and funding they need to grow and succeed. These programs are often highly competitive, and startups that are selected gain access to a wealth of opportunities that can significantly accelerate their development. In this article, well explore five key benefits of participating in a health tech accelerator program. 1. Access to mentorship and expertise One of the most valuable aspects of health tech accelerator programs is the access they provide to experienced mentors and industry experts. Health tech startups often face unique challenges, such as navigating complex health-care regulations, developing scalable technologies, and understanding the intricacies of health systems. Having mentors who have firsthand experience in these areas can provide critical guidance. These mentors often include clinicians, informaticists, investors, health-care professionals, and thought leaders. Their insights can help startups refine their business strategies, optimize their digital health solutions, and navigate the health-care landscape. With this guidance, startups are better positioned to make informed decisions, avoid common pitfalls, and accelerate their growth. 2. Funding and investment opportunities For many startups, securing funding is one of the biggest hurdles they face. Health tech innovation can be expensive, especially in the early stages when startups are working on solution development, regulatory approvals, and pilot testing. Accelerator programs often provide startups with seed funding, as well as the opportunity to connect with venture capitalists, angel investors, and other potential backers. Many accelerator programs culminate in a "demo day," where startups pitch their solutions to a room full of investors and other key decision-makers. These events can be crucial in securing the funding necessary to scale a digital health solution or product. Beyond initial funding, the exposure gained from being part of a well-known accelerator program can lead to additional investment opportunities down the road. 3. Networking and industry connections The health-care industry is notoriously complex and fragmented, making it difficult for new players to break in without the right connections. Health tech accelerator programs offer startups the opportunity to network with key leaders in the health-care and technology ecosystems, including clinicians, payers, pharmaceutical companies, government agencies, and potential customers. Through structured networking events, mentorship sessions, and partnerships with established organizations, startups gain access to a wide range of stakeholders who can help substantiate their products, open doors to new markets, and provide feedback that can be used to refine their offerings. In the health tech space, strong industry connections are often critical to gaining traction and scaling successfully. 4. Market validation and credibility The health tech industry is highly regulated and risk-averse, meaning that customers and investors are often wary of new technologies. Participating in an accelerator program can serve as a form of market validation, signaling that a startups offering has been vetted by experts and has the potential for success. The credibility gained from being accepted into a prestigious accelerator program can be a game-changer. It provides startups with a level of legitimacy that can help them stand out in a crowded and competitive market. Whether its attracting investors, forging partnerships, or securing early customers, the reputation of the accelerator can give a startup a significant boost. Additionally, accelerator programs often have ties to major health-care institutions and organizations. This can provide startups with opportunities to pilot their products in real-world health-care settings, which can serve as both a test of the products viability and a powerful proof of concept for future customers and investors. 5. Access to resources and infrastructure Another significant benefit of accelerators is the access to resources and infrastructure that startups might not obtain otherwise. These resources can include everything from access to clinical data for model building and testing, legal and regulatory support, and technology infrastructure to deploy and scale. For early-stage health tech companies, these resources can be a game-changer. Conclusion Health tech startups are at the forefront of transforming health care, but navigating the challenges of innovation, regulation, and market entry can be daunting. Health tech accelerator programs offer invaluable support by providing startups with the mentorship, funding, networking opportunities, credibility, and resources they need to succeed.

Last Wednesday, Google made a somewhat surprising announcement. It launched a version of its AI model, Gemini, that can do things not just in the digital realm of chatbots and internet search but out here in the physical world, via robots. Gemini Robotics fuses the power of large language models with spatial reasoning, allowing you to tell a robotic arm to do something like put the grapes in the clear glass bowl. These commands get filtered by the LLM, which identifies intentions from what youre saying and then breaks them down into commands that the robot can carry out. For more details about how it all works, read the full story from my colleague Scott Mulligan. You might be wondering if this means your home or workplace might one day be filled with robots you can bark orders at. More on that soon. But first, where did this come from? Google has not made big waves in the world of robotics so far. Alphabet acquired some robotics startups over the past decade, but in 2023 it shut down a unit working on robots to solve practical tasks like cleaning up trash. Despite that, the companys move to bring AI into the physical world via robots is following the exact precedent set by other companies in the past two years (something that, I must humbly point out, MIT Technology Review has long seen coming). In short, two trends are converging from opposite directions: Robotics companies are increasingly leveraging AI, and AI giants are now building robots.new effort to build humanoid robots this year. In October, the chip giant Nvidia declared the next wave of artificial intelligence to be physical AI. There are lots of ways to incorporate AI into robots, starting with improving how they are trained to do tasks. But using large language models to give instructions, as Google has done, is particularly interesting. Its not the first. The robotics startup Figure went viral a year ago for a video in which humans gave instructions to a humanoid on how to put dishes away. Around the same time, a startup spun off from OpenAI, called Covariant, built something similar for robotic arms in warehouses. I saw a demo where you could give the robot instructions via images, text, or video to do things like move the tennis balls from this bin to that one. Covariant was acquired by Amazon just five months later. When you see such demos, you cant help but wonder: When are these robots going to come to our workplaces? What about our homes? If Figures plans offer a clue, the answer to the first question is soon. The company announced on Saturday that it is building a high-volume manufacturing facility set to manufacture 12,000 humanoid robots per year. But training and testing robots, especially to ensure theyre safe in places where they work near humans, still takes a long time. For example, Figures rival Agility Robotics claims its the only company in the US with paying customers for its humanoids. But industry safety standards for humanoids working alongside people aren't fully formed yet, so the company's robots have to work in separate areas. This is why, despite recent progress, our homes will be the last frontier. Compared with factory floors, our homes are chaotic and unpredictable. Everyones crammed into relatively close quarters. Even impressive AI models like Gemini Robotics will still need to go through lots of tests both in the real world and in simulation, just like self-driving cars. This testing might happen in warehouses, hotels, and hospitals, where the robots may still receive help from remote human operators. It will take a long time before theyre given the privilege of putting away our dishes. This story originally appeared in The Algorithm, our weekly newsletter on AI.
