Rust is by far the more mature option if you're really trying to replace C++. Zig is personally interesting to me though. But if you need to write actual production critical code then you should definitely go with Rust.
Honestly, it's still a little bit surreal to me that I won't even consider C++ now for a new project after so many years of my career.
