This talk is technically not about Zig, but he still shows many of Zig's strengts: https://youtu.be/aPWFLkHRIAQ?si=b-rf_oMremovedIvAdq

To me, Zig is a language that tries to be like C, but with all the decades of mistakes removed, or rather with modern knowledge of good language design in mind, while keeping as much compatibility as possible, as to not require a lot of work for the transition as Rust did. Thus, if you're working in a C codebase, you'll be good to go to integrate Zig in as little as an hour. They also have by far the cleanest solution to macros and generics that I have seen yet (although I miss my type classes).
