This is todays edition ofThe Download,our weekday newsletter that provides a daily dose of whats going on in the world of technology.OpenAI has brought a new web search tool to ChatGPTThe news: ChatGPT can now search the web for up-to-date answers to a users queries. Previously it was restricted to generating answers from its training data, and had limited web search capabilities. But now, ChatGPT will automatically search the web in response to queries about recent information such as sports, stocks, or news of the day, and can deliver rich multi-media results.How to use it: The feature is available now for the chatbots paying users, but OpenAI intends to make it available for free later, even when people are logged out. It also plans to combine search with its voice features.The context: OpenAI is the latest tech company to debut an AI-powered search assistant, challenging similar tools from competitors such as Google, Microsoft, and startup Perplexity. However, none of these tools are immune from the persistent tendency of AI language models to make things up or get them wrong.

But if AI search becomes our primary portal to the web, it threatens to disrupt an already precarious digital economy.Today, the production of content online depends on a fragile set of incentives tied to virtual foot traffic: ads, subscriptions, donations, sales, or brand exposure. By shielding the web behind an all-knowing chatbot, AI search could deprive creators of the visits and eyeballs they need to survive. Heres what the industry should do to make AI search sustainable.This AI-generated Minecraft may represent the future of real-time video generationWhen you walk around in a version of the video game Minecraft from the AI companies Decart and Etched, it feels a little off. Sure, you can move forward, cut down a tree, and lay down a dirt block, just like in the real thing. If you turn around, though, the dirt block you just placed may have morphed into a totally new environment. That doesnt happen in Minecraft. But this new version is entirely AI-generated, so its prone to hallucinations. Not a single line of code was written.For Decart and Etched, this demo is a proof of concept. But they believe that, with innovations in chip design and further improvements, theres no reason it wont soon be possible to develop a high-fidelity version of Minecraft, or really any game, using AI.

Theyre being touted as a hot new beauty treatment, a fountain of youth, and generally a cure-all therapy for a whole host of ailments.Any cell biologist, though, will tell you what exosomes really are: tiny little blobs that bud off from cells and contain a mixture of proteins and other components. Were not entirely clear what those components are or what they do, despite the promises made by medspas and cosmetic clinics charging thousands of dollars for exosome therapies.However, there is some very exciting scientific research underway to better understand exactly what exosomes do. It might take longer for these kinds of exosome applications to get to the clinic, but when they do, at least theyll be evidence based.

It was viewed, shared, liked and commented on by hundreds of thousands of young people.Clearly, the claims were false. Why, then, did so many members of Generation Za label applied to people aged roughly 9 to 24, who are presumably more digitally savvy than their predecessorsfall for such flagrant misinformation? The answer is complex, but may partly lie in a sense of common identity with the person who shared it in the first place.
