I can agree with all your points (wrote a fair bit of Scala all though I wouldn't identify as a scala programmer).

Scala is a weird case, I would normally be the perfect fanboy for it, I like functional programming, did my fair share of SML, Haskell, Clojure. Also I am not at all dogmatic and can even find joy in writing Java.

However, Scala and I never got along well. It is - I think - too magic. I'd even prefer pure Java over it tbh.

And then, the community is fairly toxic, which also made me not want to stick around.
