I've heard great things about Zig as well. The one difference between it and Rust is the amount of industry and financial investment to date. Rust has had literally millions of dollars of buy-in from some of the biggest tech corporations on Earth, which is why I'm more confident that it will likely stick around.

This is one area where, for example, Julia has struggled. In many ways it's a fantastic language for scientific research, but it simply has never received nearly as much funding or investment as, e.g., Python.
