See that is why I eventually decided against Haskell. There are just too few Haskell jobs so investing that amount of time from a career perspective makes little sense. That leaves hobby projects. And it just does not seem to make sense to me to spend that much time on a hobby, when you got plenty of other powerful languages you can learn in a fraction of the time and do more useful stuff with.

As an academic project language it seems great, but for practical work I just don't see it.

I can do a fair amount of functional programming in Swift and Julia, but still make useful stuff without without an huge mental investment.

My life as a professional C++ programmer has made me very negative to anything involving unreasonable complexity.
