Bun의 Rust 재작성에 대한 내 생각

This analysis raises critical concerns about software engineering practices in high-stakes migrations: Bun's Rust rewrite—6,755 commits merged in just 6 days with AI-generated code and minimal human review—demonstrates the gap between test coverage and actual code comprehension. While tests verify known paths, they cannot catch subtle violations of global invariants, concurrency edge cases, or memory model inconsistencies that AI translation alone cannot guarantee. The real risk isn't Zig versus Rust, but whether production systems can safely run code that neither its creators nor reviewers fully understand.
