Zig is for people who want to write C, that's really it. It's not a replacement for C++ or Rust or Go or Swift or anything "serious".

As for why you would choose it over C, because C has too many problems for even the C lovers to ignore. Zig fixes a tiny amount of them, just enough to pretend it's not problematic, but not enough to be useful in any non-hobby capacity. Which is fine, very few languages do achieve non-hobby status after all.
