alt Hacker NewsZig is a pre-1.0 language while Rust is post-1.0. This alone is settles which one to pick for may developers. The library support is probably favours Rust too. Rust build times are much slower than Zig, I get that, but I rarely optimize software for build times.
Zig is not pre-1.0 because it’s not ready for production (bugs or missing features), it’s pre-1.0 because they want to be able to make breaking language changes.
Nowadays when you can just point an agent at release notes and have it update everything, I actually prefer not having to wait through rare major releases to get new language features.
