One of the better BHTV episodes, IMO. Robert Wright was a bit heavy on rhetoric for me: Have you sobered up? Why don't you accuse me of blah. Oh, if you are going to fling acusations around, that isn't very scientific - etc. Also the enthusiasm for extracting some kind of concession from Eliezer about updating his position at the end.
Wright gets a bit excited towards the end. It has some entertainment value - but tends to interfere with the discussion a little. It would have helped if he could have read some EY.
Interesting topics, though.
Sweet, there's another Bloggingheads episode with Eliezer.
