Except for maybe in kernel projects, C code already is old code. As far as I can tell, (modern) C++ is the oldest common language for new projects. Rust is already part of the Linux kernel, being used for rather complex things like GPU drivers in Asahi. Android rewrote their Bluetooth stack into Rust and Windows is actively replacing existing operating system components with Rust as well. I don't think we'll need to wait for Zig to start replacing old C code, it's already being replaced with Rust now. I think Zig would've been a better choice for some parts, but it's taking too long to become stable for it to be included in large projects. Still, it may be useful for people working on embedded stuff, as embedded code seems to be stuck with 90s C when it comes to language support, if someone can manage to write a compiler backend for that specific embedded chip.
