Reasons not to use Scala

Hmm... maybe you want to use Clojure? That would be a good reason not to use Scala. Or Elixir/Erlang? There are two god reasons not to use Scala.

Not to mention rxJava and Camel.

Oh, and let's not forget the most important reason of all. It's too hard to change! So just keep doing whatever you are doing. You will be like the old COBOL developers who just faded into the woodwork.
