I wish this was clickbait

Bun, the JavaScript runtime and toolkit originally written in Zig, is being rewritten in Rust using AI agents — reportedly completing a 960,000-line port in under a week. The author analyzes the implications: Bun's acquisition by Anthropic raises concerns about future prioritization, especially as Claude Code quality has declined. The Rust rewrite addresses memory safety and stability issues inherent to Zig, but the port contains 13,000+ unsafe calls, essentially making it C++ with Rust syntax rather than idiomatic Rust. The author also covers why projects like OpenCode are migrating off Bun to Node.js (Windows stability, Electron compatibility, uncertain future), and draws parallels to the TypeScript-to-Go compiler port. While cautiously optimistic, the author warns the rewrite may introduce new bugs in non-Claude-Code-critical paths that Anthropic-funded priorities may never address.
