Cursor 3 Ditches VS Code Fork for Agent Orchestration Platform — Rewritten in Rust

Fireship·high signal

Cursor 3 completely abandons its VS Code fork, rewriting from scratch in Rust and TypeScript as an agent orchestration platform. The new default view replaces the code editor with an orchestration panel where developers dispatch and manage swarms of AI agents across local and cloud machines simultaneously. The pivot comes as Claude Code reportedly captures dominant market share in AI coding, with early Cursor 3 users praising speed but flagging costs — one spent $2,000 in two days.
