The one question I wish this article answered is: what specific, quantifiable benefits could I get from using a real functional language RATHER THAN merely reactive extension libraries to an imperative language.

The point many programmers are at is far removed from diving into Haskell and hard math in functional languages. Many of us are still learning why to compose observables for multithreading. From a application programmer perspective, what could we gain by diving into FRP completely?

If Scala is the gateway drug, then the dealers need to do a better job explaining what the hard stuff actually does for us.
