One thing I'd caution you against is taking a young programmer's enthusiasm a bit too seriously. I think there's an aspect to the naiveté that winds up being tremendously helpful in long-term programming language acquisition. You sort of surrender to styles and modes of thought when you're learning new paradigms, and IMO this period winds up being something you get to repeat maybe 3-5 times in your entire career. It's a gift, the way I see it.

Is FP a "Silver bullet"? No, but it's a tremendous one to have in your arsenal. As Alan Kay once put it: "Perspective is worth 80 IQ points."

My only feedback for the OP is that I'm generally more interested in the flavors of FP than I am in FP for its own sake. If you've ever tried to build concurrent programs in C or Java, it's reasonably clear in some FP languages why things are the way they are. For instance, there are some other things worth mentioning w/r/t Clojure regarding referential transparency and the nature of values. Hash array mapped tries, the STM, concurrency primitives, persistent data structures, the ability to ignore things like lock order acquisition, and so on are also probably worth mentioning.
