This to me, is the only reply thus far that addresses what I also perceive to be the fundamental problem with Haskell - it doesn't provide any new convenient tools to solve real world problems, while requiring one learns a bunch of useless abstractions that aren't used anywhere else in industry as a default (monads, laziness, immutability)
But more importantly, immutability is used everywhere in the industry.
However the problem with the parent post of that it presumes Haskell isn't useful because of X, when clearly it's useful for many and changing X would make it not Haskell. That sort of comment isn't useful.
I think for as long as I have known Haskell (1992-) there has been interest in and a desire for a strict variant of Haskell. In 2020 it seems there are a lot more options for that, which is great, but they aren't Haskell.
this seems like some version of a No True Scotsman argument.
Should not be controversial at this point.
