Vercel CEO：Turborepo 从 Go 迁到 Rust 的 ROI 内部有争议，Agent 浪潮或改变语言选型逻辑
Guillermo Rauch 表示 DHH 关于 Rust 的看法基本正确，并透露 Vercel 已推进 Rust 化，早期项目之一是把 Turborepo 从 Go 迁移到 Rust。迁移虽已完成，但内部对投资回报存在争议：Rust 在底层 OS 访问上更适合构建系统，但人力迁移成本很高，而 Go 速度快、设计好、迭代容易。他认为随着 AI Agent 大规模出现，'对人最优'不再等于'对业务最优'，并推测 Rust 未必是终极工具链，未来可能出现更适合 Agent 时代的方案。
AI推荐理由 Vercel CEO 以 Turborepo 从 Go 迁移到 Rust 的内部经验为据，指出迁移虽完成但 ROI 内部争议大，人力迁移成本高；并提出 AI Agent 浪潮可能改变语言选型的成本结构。属于一手工程经验与观点，但为个人推文、无量化数据，且对 Agent 影响的判断是推测性表述，需保留不确定性。

DHH is fundamentally right about Rust. For context, Vercel has been undergoing a Rust-ification (carcinization, technically 🦀) for a while.
One of the first projects we migrated was Turborepo, from Go to Rust¹. The migration completed, but the RoI was actually quite controversial internally.
While Rust was in our eyes better for low-level OS access, something crucial for a build system like Turbo, the human migration costs were very sustantive.
Go is very fast. It's beautifully designed. It's easy to iterate on. We were very conflicted about the migration, because it was *humans* writing the code, *even if we knew Rust was a better choice*.
The calculus has now changed. What's "best for humans" is no longer necessarily "best for business".
FWIW, it's also quite unlikely that Rust is the end-all-be-all toolchain. I'm quite certain there's greener pasture ahead, because Rust itself was designed before the 'supersonic tsunami' of agents hit.
