As if the dating world wasn't already nightmarish enough, artificial intelligence seems to be making it worse or, at the very least, weirder.In an editorial for the Financial Times, reporter Jemima Kelly was flummoxed when a recent date admitted that he had instructed ChatGPT to write a psychological profile on her.Specifically, Kelly's unidentified suitor dispatched ChatGPT's buzzy new "deep research" tool to give him insights into her personality. The chatbot ended up spitting out a whopping eight pages of information about the reporter, who like most others in her field, has thousands of published articles for the chatbot to work with.Ironically, the ChatGPT-generated profile wasn't all that bad, with both accolades ("intellectually curious, independent-minded, and courageous in her convictions") and criticisms ("psychologically, one might describe Kelly as a [skeptic] with a conscience") that mostly made her seem astute.Initially, the reporter said she "didnt really mind" that her date had used the chatbot to profile her possibly because that first profile doesn't sound all that damning."I was a bit taken aback," she wrote, "but the fact that he had told me about it made it seem fairly light-hearted, and I thought it was a sign he was probably quite intelligent and enterprising."When it occurred to her that others might be able to use it for nefarious ends, however, she got creeped out and that was before she instructed both ChatGPT and Google Gemini to profile her for her own edification.Before having it take a crack at her, Kelly asked the chatbots whether it was ethical to psychologically profile someone without their knowledge or consent. Both suggested it was neither, with ChatGPT calling that practice "invasive and unfair" and Gemini insisting that it could "be a violation of privacy and potentially harmful."Still, when the journalist asked Gemini to provide her with a psychological profile, "it was only too happy to oblige." Indeed, that profile was less measured and generally ruder than the ChatGPT one, with the Google chatbot telling Kelly that her "directness can be perceived as confrontational" and that she was likely a stressed-out perfectionist, based seemingly on her rigor and attention to detail in her work.Though Gemini did include a disclaimer that the information it outputted was "speculative" and therefore "not intended to be a definitive psychological assessment," it didn't ask whether Kelly had provided consent to generate the profile.It's unclear whether the reporter asked ChatGPT to give her the "deep research" treatment, perhaps because that tool is only available to paying users. Regardless, it's bizarre that anyone who has enough published work online can be subjected to such nonconsensual profiling even if it's full of half-baked platitudes."Only those of us who have generated a lot of content can be deeply researched and [analyzed] in this way," Kelly wrote. "I think we need to start pushing back.""But maybe," she continued cheekily, "Im just being stressy and confrontational. Typical."Share This Article

In BriefPosted:12:51 PM PDT March 30, 2025Image Credits:Kimberly White for TechCrunch / Getty ImagesPerplexity CEO denies having financial issues, says no IPO before 2028Perplexity CEO Aravind Srinivas recently took to Reddit to address users product complaints and reassure them that the company is not under serious financial pressure.Srinivas seemed to be responding, in part, to a user theory that the company is doing horribly financially and making lots of changes to cut costs. As an example, the theorizer pointed to Perplexitys Auto mode, where the AI search engine automatically selects the model with which to answer a users prompt.On the contrary, Srinivas said Perplexity created Auto mode because all AI products right now are shipping non-stop and adding a ton of buttons and dropdown menus and clutter, which he said is not sustainable.The user shouldnt have to learn so much to use a product, he said.As for whether Perplexity is facing pressure to cut costs or IPO, Srinivas said, We have all the funding weve raised, and our revenue is only growing. In fact, he said the company has no plans of IPOing before 2028.Topics

In the heart of the Caribbean, off the coast of Belize, lies a near-perfect underwater sinkhole. In ... More 1971, Jacques Cousteaus expedition mapped its depths, uncovering clues to its ancient origins.gettySinkholes are natural depressions that form when rock dissolves or collapses, creating deep voids in the ground. While they are commonly found on land, they also exist in the ocean, often appearing as deep, circular pits in shallow coastal waters. These oceanic sinkholes typically originate from limestone caves that formed thousands of years ago, when sea levels were much lower. Over time, as rising waters flooded these caves, some collapsed, leaving behind the massive, submerged sinkholes we see today.One of the largest and most famous of these is the Great Blue Hole, located off the coast of Belize. Measuring over 1,043 feet across and about 407 feet deep, this massive submarine sinkhole was known to local fishermen for generations. However, it wasnt until the mid-20th century, as ocean exploration advanced, that it gained international attention.As interest in the worlds oceans grew, so did the curiosity surrounding this geological anomaly.Jacques Cousteau Introduced Millions To The Great Blue Hole, Thanks To His TV ShowBy the late 1960s, ocean exploration was undergoing a transformation. Advancements in scuba technology, underwater photography and submersibles were making the deep sea more accessible than ever, while a surge in public fascination driven by television and scientific curiosity was pushing marine research into the mainstream.At the forefront of this movement was Jacques Cousteau, a former French naval officer turned oceanographer, filmmaker and conservationist. Having already brought global attention to remote reefs, ancient shipwrecks and ecologically vital marine habitats, Cousteau had become a household name, blending scientific discovery with visual storytelling in ways no one had done before.In 1971, Jacques Cousteau and his crew aboard the research vessel Calypso arrived in Belize to explore the Great Blue Hole a massive, perfectly circular submarine sinkhole located in the Lighthouse Reef Atoll. This expedition was part of their renowned television series, The Undersea World of Jacques Cousteau.Though geologists already understood its karstic origins to some degree, Cousteaus approach to exploration was different. He was there to show it to the world. He was so enthralled, in fact, that he subsequently ranked it among his top ten scuba diving sites in the world.Cousteaus expedition provided the first widely publicized visual evidence that the Great Blue Hole had once been a dry limestone cave formed during the last Ice Age, when sea levels were lower. His teams footage of submerged stalactites supported existing geological theories, showing that the cave had collapsed and flooded as the oceans rose.Nearly 50 Years Later, It Took Another TV Show To 3D Map The HoleIn the years that followed, the Great Blue Hole became a popular dive site, attracting marine researchers, geologists and adventurers eager to explore its mysteries. While its striking vertical walls and massive submerged stalactites remained a major draw, divers also began documenting the varied marine life that inhabits the sinkhole, including Caribbean reef sharks, giant groupers and other deep-sea species that navigate its depths.However, a true, detailed mapping of the Great Blue Hole wouldnt happen until nearly five decades later, when advancements in sonar technology and submersibles allowed for a complete digital reconstruction of the sinkholes interior.It wasnt until 2018 that Aquatica Submarines, in collaboration with Fabien Cousteau, Richard Branson and sub pilot Erika Bergman, used advanced sonar technology to create the first complete 3D digital model of its interior.The exploration encountered a thick hydrogen sulfide layer at 300 feet, blocking out oxygen and light, creating a dead zone where no marine life could survive. Below this, the water was completely anoxic, preserving everything that had fallen in including plastic waste and dead conches, which had sunk to the bottom without decomposing due to the extreme conditions.The mapping also revealed a calcium carbonate layer at 290 feet, evidence that a thriving coral reef had once existed here before being submerged by rising seas. Additionally, divers observed sandfalls cascading down the sinkholes walls, a process that suggests the Great Blue Hole is slowly filling in over time.The expedition was broadcast live on Discovery Channel. But while the technology had changed, the mission remained the same: to explore, document and inspire a new generation to understand and protect the oceans wonders.The Great Blue Hole Is Now A Time Capsule For Earths ClimateWhile the 2018 expedition gave us the first complete map of the Great Blue Hole, scientists have since discovered that its greatest secret is whats buried at the bottom.A November 2020 study extracted a nearly 9-meter-long core of sediment from the Great Blue Holes floor, revealing a 1,885-year-long record of climate change in the Caribbean. Each layer of sediment acts like a page in a history book, showing how sea temperatures, storm activity and even human influence have changed over time.The findings confirmed that sea temperatures have been rising for nearly 2,000 years, with long-term climate patterns like El Nio and the Atlantic Multidecadal Oscillation playing a major role. The sediment also shows that hurricane activity peaked between 900 and 1300 CE during whats known as the Medieval Warm Period when storms became more intense and frequent, eroding coastlines and washing more material into the Blue Hole.But the most surprising discovery was evidence of modern human impact. The study found a sudden change in carbon composition after 1900, linked to the Industrial Revolution and the rise of fossil fuel emissions a phenomenon known as the Suess Effect. This means that even this remote underwater sinkhole, first explored for its natural beauty, is now a record of human-caused climate change.Want to see where your own climate concerns fit in to this larger trend?

ISTANBUL, TURKEY - MAY 06: A woman views historical documents and photographs displayed in a high ... More tech art installation at Salt Galata on May 6, 2017 in Istanbul, Turkey. The "Archive Dreaming" installation by artist Refik Anadol uses artificial intelligence to visualize nearly 2 million historical Ottoman documents and photographs from the SALT Research Archive. Controlled by a single tablet in the center of a mirrored room the artist used machine learning algorithms to combine historical documents, art, graphics and photographs to create an immersive installation allowing people to scroll, read and explore the archives. The SALT Galata archives include around 1.7 million documents ranging from the late-Ottoman era to the present day. The exhibition is on show at SALT Galata art space through till June 11, 2017. (Photo by Chris McGrath/Getty Images)Getty ImagesAI is fundamentally changing how software is built. Gone are the days of facing an empty editor, writing each line of code individually. While AI copilots are now common, with many powerful tools providing such functionality, and models like ChatGPT providing increasingly capable code, what is next? Enter Vibe Coding.How AI Has Changed CodeAI has had a fundamental impact on coding - simply by being able to write code from a text prompt. Prior to AI, code generation tools were largely structured and domain-specific. For example - in AI itself, one could specify a sequence of operations and have AI string together the prewritten modules that execute the sequence, adding appropriate configurations and links. Now, with just a text question, AIs like ChatGPT can select appropriate open-source modules, figure out how to link them together and present you with ready-to-run code and detailed explanations. The functionality of the code is also improving with every new release of these AIs.This ability (now also present in coding tools as a copilot function) has downstream implications for coding skills, education, and software development practices, generating such trends as prompt-driven programming, and N-of-1 Programming.What Vibe Coding AddsVibe coding, a term coined by Andrej Karpathy, drives this trend further. In particular - Vibe Coding focuses on the vibe of the software, rather than the code. The concept of using English (written or spoken) as a way to specify what code needs to be written remains, but the focus is now shifted to the overall product being created, and the role of the human in designing and guiding that through a series of conceptual directions to an AI, which result in the AI iteratively refining, fixing and adding functionality to the code. An important shift, as noted in Andrej Karpathys original message on X, is that humans may not even read these code versions - but rather assess them by their behavior on tests run by the AI at the humans behest. The observation also notes that the code can grow beyond the humans comprehension very quickly.Can You Give Me An Example?Here is the process I used to generate a simulator for a chemical reaction. I had a weeks worth of experimental data on a chemical process. I also knew the name of the chemical process that occurred. I provided this information to an AI. It was able to find the correct mathematical equations to describe the process and use those equations to build a simulator in Python.In the first iteration, the simulation did not capture the behavior in the experimental data well. I explored (using the AI) several real-world complications that may have affected the outcome. After several iterations, I leveraged my domain knowledge to select a few commonly occurring complications and asked that these be added to the simulation.This process continued (10-15 iterations) until I felt that the simulation code adequately captured the complexities of the physical experiment, and the simulation results reflected an increasing closeness to the experimental.In each case, the AI did the work of generating and testing the code, also providing concept suggestions upon request. I was the expert guide, selecting between options and making final decisions. I read the code every few iterations, but not every time.What It Means for BusinessWhether Vibe Coding is the name we will give to the future of this trend is unclear, but it is clear the overall trend is here to stay. Y Combinator reports that over 25% of its startups are now relying on AI for 95% of their code base, while Google recently reported that about 25% of its new code is AI-generated. The trend has important implications for business, raising such questions as:- Should a business be comfortable putting into production code that no human employee has ever understood? In many cases, complex code bases survive far longer at companies than the people who wrote them - so it is not exactly uncommon to have code that no one on the premises understands. However, such code usually still exists because it has proven itself over time. The idea of new code that no one understands is, well, new.- Super speed prototyping? Perhaps the best initial value/risk compromise is using this type of development for extreme-speed prototyping. Perhaps we have reached the stage where product development is not initiated just by business cases but also by quick prototypes validated by customer interaction that exist in nearly full-fledged form before production development even begins.- What does it mean for the volume of code? Vibe coding and related trends all mean that the volume of code (to be stored, versioned, and protected in an IP context for business) is growing dramatically. Businesses will need to factor this into their software development practices.- What about testing, quality, security, etc.? Production code requirements will not change because AI generates much of the code. However, how much can the developer now contribute to security and test reviews, when they can only speak to the what, but not the how, of the code?- What do software engineering teams of the future look like? It is clear that these trends benefit senior engineers, who have the knowledge to select what to build and enough instincts to detect trouble in tests even without reading the code. It does however beg the question of how future engineers will reach this knowledge level to vibe-code effectively if our learning paths (writing small bits of code, tests of algorithmic correctness) are no longer part of their job description. Personally, I do not believe this trend spells the end of software engineers (although the question has been asked). I do however believe it signals a shift from coding to software development, where the overall product (the what), and the behavior of the complex system, take precedence over who/what wrote a given piece of code.What Should Your Business Do?A few things your business should do- Ensure that your software development managers are regularly upskilled in new trends such as vibe coding.- Encourage discussion about how these approaches should be rolled out to teams, including guidelines for handling the issues above in ways that are suitable for your business.TakeawayTrends like vibe coding have significant potential to increase the speed of software development and the volume of customer-facing features developed, making it critical for businesses to follow and adapt to remain competitive. The guidelines above can help you surf the wave of AI-powered software development practically and safely.

Forward-looking: Downscaling has long been the driving force in technological progress from boosting computing power through smaller transistors to advancing display technology with micro-LEDs. Now, researchers from Zhejiang University and the University of Cambridge are pushing the boundaries of LED innovation even further, unveiling the world's smallest LEDs: nano-PeLEDs, based on perovskite semiconductors. These nano-PeLEDs feature pixel lengths as small as 90 nanometers, enabling an unprecedented pixel density of 127,000 pixels per inch (PPI). For comparison, a typical 27-inch 4K gaming monitor has a pixel density of just 163 PPI."Making electronic devices smaller is an everlasting pursuit for scientists and engineers," said Professor Di Dawei, Deputy Director of the International Research Center for Advanced Photonics at Zhejiang University.He explained that while micro-LEDs based on III-V semiconductors are considered state-of-the-art, their efficiency drops sharply when pixel sizes fall below 10 micrometers a limitation that has hindered their use in ultra-high-resolution displays.Fabrication processes of micro- and nano-PeLEDsUnlike conventional micro-LEDs, nano-PeLEDs exhibit minimal performance degradation even at microscopic scales. This resilience is attributed to their unique composition: halide perovskites a class of semiconductors more commonly associated with solar cells. "Halide perovskites are a new class of semiconductors," noted Professor Zhao Baodan of Zhejiang University. // Related StoriesCreating nano-PeLEDs, however, was no simple task. Perovskite materials are notoriously fragile and susceptible to damage during conventional photolithographic processes used to pattern LED displays. To overcome this, the research team developed a novel fabrication method involving lithographically patterned windows in an insulating layer. This technique protects the delicate perovskite material while preserving high image quality."Conventional photolithographic processes are not suitable for direct patterning of the perovskite layers it would damage the materials," said Lian Yaxiao, first author of the study, published in Nature. "This problem is overcome by our localized contact fabrication scheme."Red and green micro- and nano-PeLED pixel arraysThe team demonstrated that their green and near-infrared nano-PeLEDs maintained external quantum efficiencies of around 20 percent across pixel sizes ranging from several hundred microns down to just 3.5 microns.Even at extreme miniaturization approximately 180 nanometers the drop in efficiency was significantly less than that seen in traditional micro-LEDs. This suggests that nano-PeLEDs could outperform III-V semiconductor-based micro-LEDs in applications requiring ultra-small pixels.Efficiency of micro- and nano-PeLEDs versus pixel lengthWhile nano-PeLEDs offer tremendous promise for high-resolution displays, practical implementation requires integration with programmable circuits capable of dynamic content delivery. To that end, Zhejiang University has partnered with LinkZill, a Hangzhou-based company specializing in thin-film transistor (TFT) technology.Together, they developed a prototype active-matrix micro-PeLED display driven by a TFT backplane. This prototype is crucial to commercializing nano-PeLED technology and unlocking its potential for complex images and video playback.Images from an active-matrix micro-PeLED displayAs researchers continue refining this technology, its potential applications are rapidly expanding. The ultra-high resolution enabled by nano-PeLEDs could redefine display standards across various industries from gaming and augmented reality to medical imaging.
