For me, my preference for languages like C and Go (work and fun) and Java/C# (work only) has nothing to do with "expressiveness" - in fact, I can't even think of a language less expressive than Java - but with the fundamental truth that computers store state and programming is about modifying that state.

And when I play around with Haskell or any other functional language, I love the expressiveness, but I hate how abstracted away the actual state modifications are and how we like to pretend we live in some "pure" mathematical land without state (that sadly doesn't exist).

I love the beauty of Haskell but hate having to muck around with monads - I just want to poke that memory address right there and flip that bit thank you very much.
