We all want more powerful tools and infinite expression but at what point are we bikeshedding languages instead of building transparently clear solutions?
Scala seems to be solving problems i dont have.
As a long-time Java dev myself, Scala is solving problems you don't even realise you have, because you don't know to look for them.
Powerful types, immutable state and FP make a world of difference for writing clear solutions, with better abstractions, less code, less bugs and less bullshit than the horrendous status quo of corporate Java development.
It may take some getting used to syntax and design wise, but being able to code things up in 1/10 the size of other languages completely blows away the disadvantages of Scala.
