Rust is more a response to C++ than to C. Both C++ and rust are big and complicated languages that are good for large projects that are performance-sensitive. Both have very strong static typing and can be verbose as a result.

C feels substantially different than Rust. It’s much smaller and less complicated. It’s technically statically typed, but also not in that it doesn’t really have robust non-primitive types. It’s a very flexible language and really good for problems where you really do have to read and write to random memory locations, rearrange registers, use raw function pointers, that sort of thing. Writing C to me feels a lot closer to Python sometimes than to Rust or C++. Writing algorithms can be easier because there is less to get in your way. In this way, there’s still a clear place for C. Projects that are small but need to be clever are maybe easier done in C than Rust. Rust is getting used more for big systems projects like VMs (firecracker), low level backends, and that sort of thing. But if I was going to write an interpreter I’d probably do it in C. Now, I’d do it in Zig.

I understand why people compare Zig to C, being a simple low-level language, but I think that comparison is misleading. C++ is both more expressive than C and safer (when using appropriate idioms). Like Rust, Zig is as expressive as C++, and like Rust, Zig is safer than C++; it's just not as safe as Rust. Comparing Zig to other languages is difficult. While each of its features may have appeared in some other language, their combination, and especially the lack of certain other features, is something completely novel and results in a language unlike any other; it's sui generis.

However, unlike Rust Zig does reject C++'s attempt to hide some low-level details and make low-level code appear high-level on the page (i.e. it rejects a lot of implicitness), it is (at least on its intrinsic technical merits) suitable for the same domains C++ is suitable for. It's different in the approach it takes, but it's as different from C as it is from C++.
