Cloudflare engineer Steve Faulkner used Claude AI to rebuild 94% of the Next.js API from scratch in one week, spending just $1,100 in tokens. The result — vinext — builds 4.4x faster and produces 57% smaller bundles. His secret weapon? Next.js's public test suite served as the spec. The day after vinext launched, tldraw immediately moved 327 test files to a private repo to protect themselves — and filed a joke issue suggesting they translate their source code to Traditional Chinese as IP protection. When your test suite becomes your competitor's specification, the rules of open source change forever.

Mitchell Hashimoto (Terraform creator) says AI destroyed open source trust by enabling low-quality contributions. His solution: Vouch, a trust management system on Ghostty where trusted people vouch for others.
