9-year Rust veteran argues Zig beats Rust in the AI coding era

quakewang, who has written Rust for nearly 9 years, argues that Zig—comparable in performance and memory footprint—is the better choice in the AI era.
- Rust's strict borrow checking, once praised as a safety net for humans, now drags AI coding agents down: they repeatedly read compiler errors and take detours to appease the compiler.
- Zig's incremental compiles (post-0.17) finish in about a second, while Rust's take 10+ seconds, slowing iteration by an order of magnitude.
- Zig's explicit allocator-passing keeps boundaries clear and C libraries integrate seamlessly—ideal when AI handles basic logic and iteration speed plus low-level control are what matter.
