I think Scala's still growing - I think OCaml is too. I'm worried that between Dotty and the focus on Java 8 support in 2.12, we've gone far too long without improvements to Scala syntax, or indeed a new release at all. Having written Scala professionally full-time for 4+ years I couldn't stand to go back to a language without higher-kinded types, which pretty much means I'm stuck on Scala or Haskell.
