I've worked in a Scala shop, it was probably the lowest performing team of developers I've ever worked with coupled with the highest amounts of bragging, theoretic talk, elitism and winging about other languages, especially dynamic langues. Is this a common theme across all Scala / Haskell communities or something ?

I witnessed many times where a solution could've been solved much more efficiently using a simple Ruby or Python service of no more than a few hundred lines but the suggestion was scoffed at.

Side note, the ecosystem around Scala seemed horrible, SBT is filth and it seems to lack good libraries for most basic tasks. For something of such advertised greatness it seems there is a lot to dislike about Scala, including dragging around a JVM.
