...or full of BS.
I just quit my graduate "genetics" course because it was just shape-filling protein models with a prof waving his hands at a Plato's Cave Powerpoint screen. He's a genetics guy but genetics isn't pretty enough for Powerpoint so he spent the whole semester talking about molecular genetics, which either a) he doesn't understand or b) nobody understands. Probably both, and they definitely don't know that they don't understand it. I have better things to do with my time than listen to Just So Stories (and then Regurgitate them on the midterms). I want to go on record pointing this out, so that when the Revolution comes I'll have bragging rights.
