I was 3 years hardcore Scala, but recently went back to Java for a role. I didn't really find returning to Java to be an encumbrance at all, and really enjoyed how productive Spring Boot made me. I still love Scala and if you don't fight it and use it long enough, the crazy sounding FP/category theory stuff starts to come up naturally and seem very comprehensible. My takeaway is always avoid known bad practices, but otherwise to cut with the grain. Write Java like Java, JavaScript like JavaScript and Scala like Scala.
