I really didn't care much for this one. I usually feel like I learned something when I watch a Bloggingheads video (there is a selection effect, because I only watch ones with people I already find interesting). But I'm afraid this one was wasted in misunderstandings and minor disagreements.
Sweet, there's another Bloggingheads episode with Eliezer.
