I have use +12 langs professionally. And personally picked always some language that was not the "mainstream". I from Colombia, so not even mainstream worldwide, but probably unheard among here, much less to ship real code with paying customers. Plus, I already test a lot stuff (not just langs, but frameworks, etc). Learn from many langs that never use for more than their more basics tutorials (like kdb+) just to see what was the deal. Is like a hobby to me! But mainly, because as solo-dev anything that give me an extra advantage AND is suitable for a the challenges of a solo-dev I wanna know. So, learning not means "fully committing and betting my work on it". Is pretty certain you will learn very good stuff with Rust that will be valuable to know in general. Could be the same for Zig.
