Dev vibe-codes 20KLOC in Rust, calls it the worst language for AI-written code
rickasaurus · x · 2026-11-10
A developer who vibe-coded 20KLOC Rust projects reports the worst AI results of any language: Opus randomly adds clone(), lifetimes, Arc and tovec just to silence the compiler. His personal ranking of "write prompt, get nice code": Go tops the list, then C/C++ (huge training data), Java/Kotlin (solid but enterprise-y), Python/TS (fine small, gradual-typing abuse large), with Rust as outright slop. Quoted take: Rust is best hand-written — once you write it yourself, AI Rust is unreadable.
