You're absolutely right. The only problem with art is that art doesn't produce what is actually needed for survival (like food or practical engineering solutions), hence promoting Haskell outside of art/research is ultimately a fool's errand. But damn it is pleasant.

They already said it was helping them outside Haskell. I can confirm that my long affair with Haskell (and I still use it for private projects) did so as well.

On the other hand, it also makes for an often frustrating experience of "this would be so much simpler/easier if it were Haskell or at least had x", where x could be algebraic data types, higher order types, Monads, Applicative Functors, dependent types, laziness, and so on and so on...

EDIT: Addendum: Rust scratches some of that itch and seems more and more accepted in the workforce world, so at least that's a good direction we're moving towards.

It is a very good training/shaping tool, like mathematical analysis or modern logic. You'll benefit even if you never see an integral in the "real world". I think it should be taught in all respectable universities.

Haskell powers pandoc, a couple of trading firms, and more and more systems at FB and Google.

I don’t know if any of those things are practical but some are useful and some make money ;)

OCaml is also instructive. It’s a little more similar to “industry languages” but definitely close to Haskell; it also has reasonably broad adoption.

TontineTrust (https://tontine.com) uses Haskell for a practical engineering solution which ensures the survival of retirees that live a long life.

Your parents (and the older version of you) that are facing the 33%+ probability of running out of money in old age will agree that solving such a problem is most definitely not a fool's errand.

Otherwise fully agree.

except it works perfectly fine for practical engineering solutions soooo ??
