from the article:
'''"They can do everything monads can do, and more'''

from the message from Daan Leijen (which is referenced in the article):
I don't think that the article says that "Monads are inadequate"
'''(since monads are more general than arrows)''' but you can say
that Arrows are sometimes a better choice than monads depending
on your problem domain.

This is as contradiction, monads are more general but can do less?
