Will discusses a fascinating phenomenon where a July tweet inventing plausible AI infrastructure jargon—specifically "fork caching" for the massive number of repos created by coding agents—became a reality in August.

Cursor launched Origin, its agent-oriented Git hosting service. Its architecture closely mirrors the joke: Cursor explicitly addresses agents creating "millions of tiny repositories," treats local copies as a cache, stores durable history in S3, and rematerializes inactive repos on demand. This highlights the real impact of agent workflows on infrastructure.
