Cursor is building Composer 2, its own model designed to autonomously execute lengthy multi-step coding tasks — no longer content to be an API wrapper. The layer that buys frontier intelligence and resells it is getting thin; AI-native tooling companies are vertically integrating to own the model, not just the UX.
📉 Tech Layoffs Top 45K in 2026 — One in Five Explicitly Attributed to AI

This isn't OpenAI building better AI on top of developer tools; it's buying the foundational layer those tools run on, then building AI on top. Platform lock-in through infrastructure ownership is the oldest playbook in enterprise software.
