I use Scala frequently for internal microservices development. I also write a fair amount of Clojure. I believe that a lot of good and robust software is built in Scala, but that it suffers from a kind of complexity fetishization that offsets, for debugging purposes, a lot of the positive effects of robust typing. Compiler speed is also a problem for me personally.

Given my choice of options, I will choose to build new systems in almost any other JVM language, including stock Java 8. However, the language isn't going anywhere, and is worth learning. I find that feedback is fastest in Clojure. Your mileage, as always, may vary.
