Scala is awesome. It is meant to be a scalable language where you go from level 1 to say 5 as you learn. Problems arise when you put a level 5 guy into a level 1 team and letting him loose. No common style guide, no team training, just write those type signatures approaching tweets max length and let the rest wonder wth is going on
I'd argue that the real problem is finding people who think they're level 5 but aren't. Writing dense impenetrable code certainly doesn't sound like a high-level engineer to me!
Scala certainly has no shortage of these people, but at my work we throw senior engineers with zero Scala experience or training at the language and it generally turns out OK. Turns out that a 10x faster Python or a 10x more concise Java are selling points enough, even without any fancy code!
