FWIW, I think there's a lot of people out there who would claim that Scala is a bit of a step backwards for the professional community. It's a fine language, but not a (socially) scalable one due to it's immense expressiveness.

Scala is rough IMO less because of the expressiveness, but more because you have at least 4 paradigms in common use, none of which play well with each other. Let's see, I count (1) Futures/Async (2) Threaded (3) Akka/Play/Actors (4) Finagle, (5) Reactive Streams.

There are so many impedance mismatches between them and so many diamond dependency conflicts that it's impossible to get any moderate size project done without going to microservices so that e.g. your Redis client and your HTTP server aren't complaining about different subtly incompatible versions of Netty.
