Claude改寫Bun引發Zig反擊. 本文保留已核驗事實，並以產品、基礎設施與治理脈絡重新整理。
發生了什麼
Claude改寫Bun引發Zig反擊 is the current news peg. The verified record centers on these points:
- Bun moved from 535,496 lines of Zig plus C/C++ pieces to a Rust codebase with more than 1,009,272 changed lines
- the migration used up to 64 Claude instances in parallel workflows
- the disclosed API cost estimate was about $165,000
- roughly 4% of Rust code remained in unsafe blocks after the migration
為何重要
更大的產業訊號是 AI can lower the entry cost of large migrations, but maintainability and community trust are settled later.
接下來看什麼
接下來要看的重點是 whether the Rust version keeps performance gains while reducing unsafe code and easing contributor onboarding.
