For many languages I agree, especially languages with steep learning curves (e.g. Rust, Haskell). But zig is dead fast to learn so I'd recommend just nipping through Ziglings and seeing if its a language you want to add to the toolbox. It took me only about 10 hours to pick up and get used to and it has immediately replaced C and C++ in my personal projects. It's really just a safer, more ergonomic C. If you already love C, I maybe wouldn't bother.
