Why Rust is the Ideal Language for Vibe-Coding
summary
Claims that Rust’s compiler stops thread-safety bugs before they ship: compile errors name the unsound type and direct the fix rather than letting a model introduce intermittent data races. Demonstrates a 100 threads counter where TypeScript might run and intermittently fail but Rust refuses to compile, pointing out RC RefCell<i32> is not Send so the agent must swap in a thread-safe type. Argues compile-time feedback beats test-only loops and is faster and more reliable than an agent review.
