Fogified

Could someone tell me, please, just when it was I became an old fogey?

Because I went to a talk today, and I've either become an old fogey or the speaker was BSing something awful. Some of the other folks in the audience were nodding as if the speaker were saying smart things, things that made sense and were groundbreaking. But I kept hearing jargony emptiness and the sound of self-congratulatory name-dropping.
