That has been my very limited experience as well, but with Scala I'm still things will get out of hand. The only "new" language I feel confident would not disappoint or surprise me negatively down the road is Golang.
The language is large, supports multiple paradigms and in general allows many different ways to express the same thing. That's great for short term productivity and/or small and tightly knit teams, but I worry about less ideal conditions. In theory a strict and well defined style guide should take care of that (I have used them successfully in C++), but I feel with Scala that will not be enough. Expressed differently: Scala is a great language for smart and careful programmers, but a ticking bomb for the less talented masses.
Golang, in comparison, is very transparent, WSYIWYG.
