I wouldn't frame it so dire as you have. For me, I see value in learning one systems-level language well to round out my generally higher level language focus.

I wouldn't frame it so dire as you have. For me, I see value in learning one systems-level language well to round out my generally higher level language focus. I never used Go, so choosing Rust for this was easy. Go does not satisfy some tasks in the way that Rust does, but Go likely does just fine for the reasons you originally learned it. However, I do see Rust as the best way to broaden my horizons and career opportunities. Suddenly, realms where C and C++ would be used exclusively, I can now more easily play in. Many times, Go would not qualify for these types of projects because of its garbage collector. So from language tooling to browsers, learning Rust may help me debug issues down the stack or help me creatively solve performance issues by plugging it in, and that feels like a win to me and wholly worth the price (or is it pain?) of admission. First class WASM support doesn't hurt either.
