In the end, Haskell's ramp up time (to be productive) will slow it's momentum, and I feel that's with all languages with a ramp up time. Most popular languages have a pretty low ramp up time, and part of that is business concerns (getting a whole team to being productive in a language with a long ramp up time takes...well, time, and it's rarely the right option to have them make that transition), but also the personal, human side of it - we suck at being bad at things and the experience of it is hard to push through for people. Actually, jumping back into mathematics outside of work, I'm having to go through this period of uncomfortable 'badness' and resisting my urges for the greater good. It is emotionally taxing to be 'bad' at something. I think that's part of why we favour languages that allow us to be productive quickly, despite it probably paying off in the long run. I wouldn't do it with everything (you need quick wins _somewhere_) but it's a good skill to have, to be disciplined and persevere despite what your heads saying. I'm no psychologist though, so this is largely conjecture and anecdotes.
