Not sure why you are getting downvoted, but I agree. There is a learning curve to Haskell, which should not be surprising. Haskell is to Python what Python is to x86 assembly. x86 assembly has less of a learning curve than Python. There's less to learn and it's much more flexible.

Once the learning curve has been overcome, most would agree that higher-level languages are more productive. I am significantly more productive in Haskell than Python, especially for any non-trivial problem.
