For now, I have a basic grasp of C#, a little Python, a little C++, and a little TypeScript. I also know Java to some extent, but honestly, what I mostly build is CRUD app assembly. To go deeper, I think I need to dig into a systems language. But I'm not sure whether to invest in Zig or Rust.
So unless you work in another domain where you do a lot of low level programming, then every time you drop down you will be out of practice. This favors using a simpler low level language, with low friction for integration. Rust and C++ don't handle being used infrequently, but C with it's simpler standard library and syntax fits this nicely. But it doesn't have things you expect for a modern programming language, and it is also has a lot of dangerous footguns that are easy to forget if you are out of practice
In comes Zig. It's low level, comes with it's own toolchain that makes it pleasant to work with, easy to cross compile, has more safety features built in that C, but is not overly complicated. The code tends to be more verbose, but also more straightforward. So it's a perfect language to pair, when you know you won't be able to do everything in a high level language.
For me that's what seals the deal. I'd argue that Odin has a nicer syntax, but there is a reason that tools like cargo-zigbuild^1 exists. The fact projects not related to Zig are willing to ship Zig toolchains to make lives easier is a testament to how seriously Zig takes this.

Most of such code is still written in C.
But honestly, if you just need to squeeze a little bit more performance, you should check the non-GC part of C# first (ArrayPool, Span, stackalloc).
I don't think in your shoes I'd prioritize learning Zig for any of these domains, though, for a few reasons:
* It's not a pre-req for understanding some existing corpus of important software (which is a big reason for C and C++ in 2026) or the language of choice for some current hot domain (as Python is for AI).
* It's not memory-safe, which (whether via GC or Rust's borrow checker) is increasingly viewed as a critical security attribute.
* It's not stable yet, so I'd expect a certain amount of running to keep in place both in your learning and in avoiding bitrot in anything you write in it.
* From the outside, the community seems strangely hostile as well as elitist.
A few I might suggest instead: Rust (both as a language I personally like and as the most different from the ones you've already touched), Go (which is a good choice for employability), SQL (maybe you already know this one if you're doing CRUD stuff but you didn't list it), bash, and more Python and/or TypeScript.
Zig is a very interesting and well built language, but it is also niche, unstable and not offering radical improvements over C.
C, as the foundation of all modern kernels and system tools, among many other things, is extremely unlikely to go away soon.
Everything you do in Zig can be done almost in the same way in C or C++.
I would say the real value of Zig is in the standard library that is more modern and arguably better.

Personal thoughts: I think Zig will become more stable once 1.0 tag released. Currently I cant find a fix to my error in net. But the folks on Zig Discord server helping me out.
With this in mind: Does anyone here program in Zig, or know someone who does who is not a current C (or C++) programmer?
I think Zig does, specifically because of its build system and it's C interopt story. Plus Zig has the added advantage that learning it teaches you about how the computer works, how memory gets laid out, etc. So even if it never gets wide adoption the skills are highly transferable.
Just because people don't like this doesn't mean it's not true.
