Three threads from today's feed: collaboration tools are bending toward agents, a founding figure of reinforcement learning is questioning the field's favorite shortcut, and the cybersecurity job market is splitting along an experience line. Slack Code turns chat channels into shared workspaces for coding agents. The

Two product launches and a privacy reckoning lead the AI desk today. Meta is now one of Microsoft's largest AI customers, spending hundreds of millions of dollars a year on Azure to run trillions of AI tokens every week. According to a Bloomberg report carried by Techmeme and

Two stories today point at the same quiet shift — the moat in AI is moving from raw model power to the machinery around it. A large-scale autonomous-research experiment shows cheap open models closing in on the frontier when paired with the right harness, while a Chinese AI-OS

Two Chinese tech giants moved on the same morning to push AI deeper into the products ordinary users and enterprises touch daily: Tencent rebuilt its database layer around agents, while Baidu made its office agent free for everyone inside the search app. Tencent Cloud has rebuilt its database stack around

Fields Medalist Terence Tao argues in a new essay that AI is about to force mathematics to confront questions it has spent a century avoiding — and the reckoning could be as destabilizing as Gödel's incompleteness theorems. Tao's central claim is that AI will soon handle a

Michael Burry, the investor who famously shorted the housing market before the 2008 crash, is now betting against Nvidia's dominance in AI chips — and he has a specific name in mind. Burry highlighted Etched, a Harvard-dropout-founded startup, as presenting "serious competition" for Nvidia in

Chinese autonomous driving is going global — and Uber is the delivery vehicle. Pony.ai and Uber have launched Europe's first commercial robotaxi service, starting with Zagreb, Croatia, as part of a plan to deploy over 2,000 driverless vehicles across five European cities. The service went live on

A major Chinese tech leader just drew a hard line on AI shortcuts, while global model pricing gets bloodier and a viral AI tool gets exposed as fraud. ByteDance founder Liang Rubo has told staff to avoid using distillation on the company's AI models, even if it means
