I've heard good things about Zig. I want to pick it up and experiment with it but at ~2% market share I find it hard to justify spending the time to learn and master it right now. It's usually much easier to find the time to learn a new language if there is a project (work or open source) that is also using it.
It can be useful sometimes to learn things irrespective of what the rest of the world thinks of them.
My personal experience was (back in 2017/2018) that Zig was basically a language you could learn in a weekend and end up being reasonably productive after a week. With that in mind, you might find that you can try it out and either find something that you really like in it and continue, or simply drop it (I ended up picking Odin over Zig, for example, and have found it delightful even 1+ years into production).
The truth is that if you only ever learn what is already popular you'll end up being the professional equivalent of a gray mass with zero definition and unique value proposition.
