Let's not forget F# and OCaml. Places like Jane Street become very attractive for the sake of working with OCaml and (presumably) people with a high level of skill. Haskell is very attractive. Good run-time performance, the ability to avoid common errors through higher-order functions, and the ability to abstract complex patterns. I looked into Rust and Kotlin a month ago for a Summer coding project. They were intriguing but not enough to choose. I wound up going back to Scala, which I'd set aside for a couple of years. (Scala pays some tribute to ML as well.) I may go back to one of them at some point.
