Ask HN: What's next after the FP trend

There has been a significant buzz around FP on the latest years, from purely functional languages being adopted again (as Haskell), and also from relatively new languages as Scala / Clojure being used in large scale applications (as well as the brand new stacks which are emerging with it).

How do you see this trend?

Given it is not a new paradigm, are we surpassing any problems that showed in the past?

What you think is next after the current trend?
