Who needs a supercomputer when you can calculate pi with a box of sewing needles? Happy Pi Day! March 14 is the date that otherwise rational people celebrate this irrational number, because 3/14 contains the first three digits of pi. And hey, pi deserves a day. By definition, it's the ratio of the circumference and diameter of a circle, but it shows up in all kinds of places that seem to have nothing to do with circles, from music to quantum mechanics. Pi is an infinitely long decimal number that never repeats.

The company launched its Sora 2 model in September 2025 alongside a dedicated Sora app. OpenAI plans to add its Sora video generation model directly into ChatGPT, reports . The standalone Sora app was seen as a smash hit when it launched alongside Sora 2 in September 2025, but interest in the video generation app has fallen in the time since as users ran into limits on the amount and kinds of videos they could create. Adding Sora to the ChatGPT could give the model a second life, and ideally grow the ChatGPT app's weekly active users from the 900 million OpenAI reported in February, to a billion or more. According to, the standalone Sora app will stick around after the model is integrated, even though the app has fallen out of the App Store's top 100 free apps and only a small number of users reportedly share their videos publicly in the app.

This month we tackle the topic of young people and what AI tools mean for their future. Joining the conversation this time are: Sanmay Das (Virginia Tech), Tom Dietterich (Oregon State University), Sabine Hauert (University of Bristol), Michael Littman (Brown University), and Ella Scallan (AIhub). As AI tools have become ubiquitous, we've seen growing concern and increasing coverage about how the use of such tools from a formative age might affect children. What do you think the impact will be and what skills might young people need to navigate this AI world? I met up with a bunch of high school friends when I was last in Switzerland and they were all wondering what their kids should study. They were wondering if they should do social science, seeing as AI tools have become adept at many tasks, such as coding, writing, art, etc. I think that we need social sciences, but that we also need people who know the technology and who can continue developing it. I say they should continue doing whatever they're interested in and those jobs will evolve and they'll look different, but there will still be a whole wealth of different types of jobs.

PCWorld reports that OpenAI plans to integrate its Sora video generator directly into ChatGPT, making AI video creation more accessible to users. This integration could lead to changes in ChatGPT's subscription plans and pricing structure due to the high costs of running video-based generative AI.

The Download: how AI is used for military targeting, and the Pentagon's war on Claude Plus: an ex-DOGE staffer has been accused of stealing social security data. The US military might use generative AI systems to rank targets and recommend which to strike first, according to a Defense Department official. A list of possible targets could first be fed into a generative AI system that the Pentagon is fielding for classified settings. Humans might then ask the system to analyze the information and prioritize the targets. They would then be responsible for checking and evaluating the results and recommendations. OpenAI's ChatGPT and xAI's Grok could soon be at the center of exactly these sorts of high-stakes military decisions.

China's OpenClaw Boom Is a Gold Rush for AI Companies Hype around the open source agent is driving people to rent cloud servers and buy AI subscriptions just to try it, creating a windfall for tech companies. George Zhang thought OpenClaw could make him rich, even though he didn't really understand how the viral AI agent software worked. But he saw a video of a Chinese social media influencer demonstrating how it could be deployed to manage stock portfolios and make investment decisions autonomously. Zhang, who works in cross-border ecommerce in the Chinese city of Xiamen, was intrigued enough that he decided to try installing OpenClaw in late February. Zhang is one of the many people in China who got swept up in the craze over OpenClaw recently.

Three Mile Island's cooling towers have until recently served as grave markers for America's nuclear-power industry. A s we drove through southwest Memphis, KeShaun Pearson told me to keep my window down--our destination was best tasted, not viewed. Along the way, we passed an abandoned coal plant to our right, then an active power plant to our left, equipped with enormous natural-gas turbines. Pearson, who directs the nonprofit Memphis Community Against Pollution, was bringing me to his hometown's latest industrial megaproject.
