The Pulse: Industry leaders return to coding with AI
Mark Zuckerberg and Garry Tan join the trend of C-level folks jumping back into coding with AI. Also: a bad week for Claude Code and GitHub, and more
The Pulse is a series covering events, insights, and trends within Big Tech and startups. Notice an interesting event or trend? Hit reply and share it with me.
Today, we cover:
Founders back coding with AI: Mark Zuckerberg & Garry Tan. The Meta chief is shipping diffs after 20 years, while Garry Tan at Y Combinator is knee-deep in coding, 15 years later. Founders with technical backgrounds being hands-on with AI agents could be a good thing – especially when the “honeymoon” period ends.
A bad week for Claude Code and GitHub. Claude Code’s source code was leaked when a sourcemap file was accidentally uploaded, and revealed that the tool uses anti-distillation to deal with competitors, and also some potential future features such as an always-on background agent. Also: DMCA copyright strikes from Anthropic raise a big question: can a codebase that is fully AI-generated be covered by copyright?
Industry pulse. Meta sets targets for AI-generated code, GitHub’s 6 years of reliability issues, massive job losses at Oracle, GitHub Copilot rollouts and then rolls back ads, RAM prices fall (for now), and more.
