Nvidia concedes the Chinese high-end AI chip market to Huawei as U.S. export controls tighten, while simultaneously facing a new ban on its RTX 5090D v2 consumer GPUs entering China. This marks a critical inflection point in the global semiconductor war, as Nvidia’s absence accelerates China’s push for a self-sufficient, localized AI ecosystem and independent computing infrastructure.

Tech & AI#

Tencent’s new OS-level AI assistant “Marvis” has officially launched, capable of deep system control and cross-device coordination across Windows, Mac, and Android. In the hardware race, Nvidia’s CEO is betting heavily on “Agentic CPUs” with the new Vera chip, projecting $20 billion in CPU sales this year and opening a potential $200 billion market for AI agent execution. Similarly, Intel is strictly enforcing an “A0 to production” mandate to fix historic yield issues ahead of its 14A node launch in 2028. Meanwhile, Meta is laying off roughly 8,000 employees to funnel resources into its AI ambitions. In the startup space, Anthropic expects its first profitable quarter as it negotiates to adopt Microsoft’s custom Maia chips to reduce reliance on Nvidia. On the regulatory front, President Trump has delayed signing an AI executive order over fears it could slow U.S. AI development and give an edge to China.

Datasette Agent Simon officially announced Datasette Agent, a conversational AI interface that lets users ask questions of the data stored in Datasette. The post features a live demo using Gemini 3.1 Flash-Lite to successfully query a blog database to find a bird-watching record. He highlights a growing plugin ecosystem—including charts, image generation, and sandbox execution—and notes that tools like Claude Code and OpenAI Codex are proving excellent at writing these extensions. Looking ahead, Simon teased a major refactor for his LLM library, a Claude Artifacts-style plugin, and a personal AI assistant named “Claw” built using his older Dogsheep tools.

Software engineering at the tipping point by Google for Developers. Why: A highly pragmatic, sobering look at how a 10x increase in AI-generated code will completely break our current CI/CD, testing compute, and human code review pipelines unless we immediately adopt rigid “software ecology” and systems thinking.

To scale coding agents reliably, Dropbox realized that AI tools must be seamlessly integrated directly into the organization’s existing hermetic test, build, and validation environments rather than operating as standalone iteration environments. By forcing their internal “Nova” agents to propose code and then handing control back to a deterministic platform for CI testing, Dropbox prevented runaway AI loops and ensured that generated code survives real-world validation constraints.
