I actually think it has a lot to do with the runtime and perhaps a little with compilation time.

Compared to the JVM languages I would choose Haskell any time (if given the choice), but for most native tasks the "burden" of Haskell's type system and mediocre performance makes it hard to pass the "value return" threshold compared to Go, Nim, Rust or even C++.

I'm sure that Haskell's performance is plenty for most applications, and the low level/unpure escape hatches are there, but they also raise the complexity significantly from that I have seen.

To me Haskell still has an aura of language research.

This may be a prejudice assumption, I have not done anything more than toys with it.
