3 months building production apps with AI coding tools

After 3 months of exclusive AI-assisted development using Google Antigravity, Cursor, Windsurf, Cline, and GitHub Copilot, I wrote up my experience.

Key insights: - Antigravity's multi-agent orchestration is genuinely novel - The "95% correct" problem is real and expensive - I nearly shipped a timing attack vulnerability in AI-generated auth - "Vibe coding" is both revolutionary and dangerous

I've built dozens of vibe-coded apps in the past 2 years. Absolutely zero sales.
