For an uninitiated, learning Java takes about the same amount of time as 
learning Haskell. Learning monads is like learning Spring or one of the 
gazillion other library frameworks out there in the Java world, so even 
that isn't much of a difference.

If you're a programmer already, then changes are that Haskell is indeed 
harder to learn than most other languages you might want to learn, 
because the overlap of standard concepts and techniques is smaller.

IOW it's harder to teach Haskell to programmers than to nonprogrammers.
Which also means that our conclusions from our experience as programmers 
do not predict much about Haskell's future.

This can be avoided if you find a job that has a 50-50 split of Haskell 
and non-Haskell work, but that's not always possible and I agree this 
can become a huge problem.
