Earlier quoted context omitted.
Having worked with Scala I disagree it’s a safe choice. Scala is a huge, complicated, difficult language built on the huge (but very powerful) JVM. It’s also hard to hire Scala devs AND hard to train non Scala devs to write Scala, because it’s not a language you can learn in a weekend. (Speaking from experience)
Also speaking from experience: Scala takes much less time to learn if you have someone familiar with regular programming concepts (not FP religion) to decode it for you. But ultimately agree, it's a bad choice for pretty much any purpose.
Maybe if you're familiar with something like Haskell Scala is more straightforward to decode?
