Could you build this?
No Cursor is a heavily modified native desktop IDE fork of VS Code with custom model fine-tunes, low-latency diffing engines, shadow workspaces, and custom agent infrastructure operating at extreme scale.
What it would actually take: A real build requires forking VS Code (Electron/TypeScript/C++) and modifying the core text buffer and language server protocol (LSP) layers to intercept keystrokes and diffs in real-time. Key technical hurdles include developing a low-latency speculative decoding infrastructure, maintaining a synchronized virtual AST context of massive repositories, and running remote headless agent execution environments. It requires world-class systems programmers, deep compiler knowledge, and massive GPU compute budgets for custom coding models.
