My Thoughts on the Bun Rust Rewrite

Andrew Kelley, creator of the Zig programming language, shares his perspective on Bun's rewrite from Zig to Rust. He recounts the history of Bun's relationship with the Zig Software Foundation, criticizing Bun's poor code quality, management culture, and engineering practices. He expresses relief at the Rust rewrite and Anthropic's acquisition, as it severs a relationship he viewed as a net liability for Zig. He also rebuts several claims in Bun's official blog post, including assertions about fuzzing, LTO performance gains, and binary size improvements, arguing these were engineering failures unrelated to the language switch.
