On Wednesday I debated my ex-co-blogger Eliezer Yudkowsky at a private Jane Street Capital event (crude audio here, from 4:45; better video here [as of July 14]).
I “won” in the sense of gaining more audience votes — the vote was 45-40 (him to me) before, and 32-33 after the debate. That makes me two for two, after my similar “win” over Bryan Caplan (42-10 before, 25-20 after). This probably says little about me, however, since contrarians usually “win” such debates.
Our topic was: Compared to the farming and industrial revolutions, intelligence explosion first-movers will quickly control a much larger fraction of their new world. He was pro, I was con.

I am not so confident of this. There were a bunch of early hominids, other than H. Sap, whose intelligence is not well established. Suppose, say, it turns out that Neanderthals were 7% smarter on average than modern humans, but lost out evolutionarily because they had too much body hair. What would that imply about the importance of intelligence?
Actually, we have strong reason to suspect Neanderthals were smarter than Cro-Magnon man, and lost out because Cro-Magnon man traded and Neanderthals didn't.
