> scala/functional engineers are also more likely to focus their energies on monads and type theory rather than product delivery This feels to me like a low effort and vague criticism. Essentially, this is a complaint about an arbitrary group of developers that they're playing around with tech (whatever that tech might be) instead of delivering... Obviously, in this case you can't say that specific thing about Python/JS/PHP/whatever developers, because "monads and type theory" just don't apply in these languages. (I know Python has MyPy, but let's put that aside for the simplicity of the argument.) But for some non-scala/functional engineers, somebody could complain that they're wasting time playing with GUI frameworks, testing frameworks, async libraries, whatever... The truth is, people can clown around with any technology, just as people can deliver with Scala/FP or something else.
