I think every company should open source their code.

A strong argument for why companies should open source their software, framed around the emerging 'building block economy.' The core thesis is that AI agents prefer open, modular, well-documented components over closed commercial software, and that the future of competitive advantage lies in letting customers fork and customize your product rather than building every feature yourself. Uses T3 Code's 1,500 forks and Mitchell Hashimoto's Ghosty/libghosty growth data as evidence. Also introduces the concept of a 'patch.md' file — a plain-English description of user customizations that enables AI-assisted merge conflict resolution when upstream updates break forks — as a path toward self-forking, self-healing software.
