HashiCorp 創辦人 Mitchell Hashimoto 針對 Bun 從 Zig 改寫為 Rust 發表看法。他指出，過去程式語言具有強大的「鎖定效應」，但如今已變得高度可替代（fungible）。Bun 證明了他們能在短短一兩週內將程式碼移植到任何語言，這意味著在 AI 與代理工程（Agentic Engineering）時代，程式語言只是工具，隨時可以被拋棄與替換。
HashiCorp co-founder Mitchell Hashimoto shared a thought-provoking perspective on the news that Bun — the popular JavaScript runtime — is being rewritten from Zig to Rust. He argues that programming languages used to carry an extremely high "lock-in effect": once a project committed to a particular language, the cost of switching was prohibitively high. But this reality is undergoing a fundamental change.
