> It's a dad-joke that he told at a talk. Heaven forbid the man try and add some levity to situations.
It's not funny. Anyway, like I said, it's a performance. The fact that you (and he) would agree with that judgement doesn't make it any less damning. I watched part of a lecture he did on youtube. Absolutely unwatchable. If he has a point he's unable to communicate it. But the real point is mystifying the audience, creating the impression that they're witnessing a genius thinking out loud, and the terrible jokes don't help.
