Interesting - I mentally parsed that as "easy to try in my environment" and skipped right by the implication of "on the JVM it's very easy" as a Clojure/Scala degree-of-difficulty qualifier.

I actually found this article from a non-technical recruiter informative and do respect this effort from the author. It's nice to read from a recruiter who has taken, at first glance, a deeper look at functional programming in the marketplace and shares some insights. There's some hyperbole in the article, but it seems to be coming from a honest perspective.
