Cursor replaces VS Code as the default IDE for AI-native teams.

What: AI-native fork of VS Code with built-in chat, agent edits, and full codebase context in one window. No copy-paste loops between editor and chat tabs.

Why it matters:
• Engineers ship 30-40% faster (multi-file edits, refactors, code review in terminal)
• Solo founders now handle work that used to require contractors
• $20/seat/mo vs hiring junior dev at $60K+/year
• Cursor adoption jumped 60% YoY among seed-stage teams (Waveup audit of 600+ startups)

How it happened:
1. Anysphere (Cursor team) forked VS Code in 2023, added Claude API integration
2. Shipped ⌘K (in-place rewrites) + ⌘L (repo-aware chat) — solved context-switching tax
3. Agent mode (multi-file planning) shipped Q4 2025, became default for refactors
4. GitHub Copilot added agent mode in 2026, but Cursor's UX stayed tighter

Takeaway: If your team codes without Cursor in 2026, you're shipping slower than peers on the same budget.
