I use Rust and C at work. I quite enjoy Rust, but I currently have no reason to believe C won't outlive it, by a lot.

Correct me if I am wrong, but C is the “greatest common denominator” for several decades already. Java, .NET, go, Rust are very much ecosystems-in-themselves. From the practical standpoint, they can not use each other’s code, but they all can use C libs.

Technically it's only the C API that's important, the implementation behind the C API can be written in any language. The downside is though that you still need a language toolchains X, Y, Z to compile the implementations. Transpiling everything to C removes that one dimension from the build process.

Zig has been in the news a lot recently but I haven't explored it much other than a few tech talks which seemed interesting.

I wonder if this is it's killer feature - compatibility with the C ABI.

> compatibility with the C ABI

Almost all non-C language offer that feature. The additional thing of the Zig toolchain is that it can also compile C/C++/ObjC projects without requiring a separate compiler toolchain, e.g. the Zig compiler toolchain is also a complete C/C++ compiler toolchain.

Almost all languages provide a method of calling C generated code for sure. But, as I understand it, this is usually a more tortuous path than straight ABI compatibility.
