I expect you were exposed using a heavily functional programming approach. That's a whole 'nother (larger) area to pick up along with the different language. If Scala is used as a "better Java" to start with, and then the developers explore FP at their own pace, I think there's a better outcome. Granted Java 8+ has done some to close the gap with Scala as well. I wonder if Scala-Native will absorb some Rustish features as other languages have or are attempting to... (What I said above echoes Odersky's ideas about Scala developer levels: https://www.scala-lang.org/old/node/8610.html https://www.scala-lang.org/old/node/8610.html)
