I tried Haskell, but I found it unreasonably complex to be practical. I only learn programming languages if I have a practical reason to use them, so I never picked it up again. Perhaps you have a point, everything is relative.
Try writing a programming language with Haskell. Learning Haskell changed the way I view things and most other languages feel cumbersome in comparison.
There’s something almost magical about writing software in a language like Haskell, when you have defined good and elegant abstractions, it’s as if you peer into the matrix and touch the divine.. so to speak.
I recommend that you broaden your horizons by studying something really complex like Haskell and something really simple and stripped down like Lua.
