Haskell is neat, and is one of those things I'll regularly come back to play with in my spare time. A lot of the ideas behind it have made me a better programmer. Rust I've never touched, though it looks interesting. But:
- In my daily work, the work that pays my bills, I regularly use software built in Rust, eg ripgrep.
- About the only time I ever cross paths with Haskell is in those times when I'm going out of my way to do so as part of my tech hobbying.
I think that's an important difference
