I think I can rephrase my opinion for either the language or concept and still agree with it. I believe Haskell has continuously become more developer friendly and may some time reach some kind of friendliness and use case support threshold that allows for a wider adoption.

I recently started looking at Haskell a couple of weeks ago after years of hiatus. The IDE support have gone from almost none-existing and/or bug ridden to almost as good as Java and the new package manager has so far been pleasant to use. Although I'm using it for small side projects so it might not be fair comparison to my day work use case.
