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:

  1. 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.

  2. 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?

  3. 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.

Two interesting stories of AI tools encouraging busy founders to start writing code again with AI agents.
