I think you just won this thread. Seriously, I agree very much with your sentiment. The question isn't so much about the very latest-and-greatest new technologies per-se, but rather about the applications of technologies that are quite often fairly old. That's not to say that there isn't really cool stuff just over the horizon, but as you say, we really need better applications more than more new tech.
And sometimes the tech we need is "out there" and has been for a while, but just hasn't hit "critical mass" yet.
Take @kroltan's answer. I am also extremely bullish on RDF, Wikidata, and the like. But most of this stuff is pretty old now, especially in "Internet years". Which leads, of course, to the question of where the line is between incremental refinement of "old tech" and actual "new tech" as a discrete thing.
