Rust, because I finally made it from beginner to intermediate level (at least I think).
https://flix.dev/ looks very cool.
Also, recently someone posted this here on HN: https://github.com/coalton-lang/coalton
It's a statically-typed, functional language embedded in Lisp, with many of the FP goodies.
Secondly, the ones that are new. Not Rust, Go, or even Carbon or CPP2 new. Not new like academically new. New like some practical one I haven't heard of yet. I'll know it when I see it (like Rust or Go 10 years ago).
So not Rust, but Lisp, pony, Concurrent Pascal and all it's derivates.
