Even a "perfect" language is faulty if the barriers between its current state and mass adoption are insurmountable.
Completely reform education in this country to make purer languages like Haskell more palatable for younger generations than, say, PHP, and I'll totally be wrong in 50 or so years.
I'm arguing that "Python is easier" is false, simple as that.
- Beyond toy examples, writing Python isn't easier. Writing reliable, easy to maintain, bug-free Python programs is just as difficult, and your average person won't be able to do it right off the bat.
- You don't need to really know what a monad is in order to write Haskell as a beginner; that's a red herring.
If you want to argue that it's easier to write toy examples in Python, without regard for good programming practices, then... it'd still be debatable: if I remember correctly, some years ago there was a post here about someone teaching Haskell to highschoolers, to great success. They found it fun and easy.
