"I have a feeling that if the loser of the AI Box experiment were forced to pay thousands of dollars, you would find yourself losing more often."

David -- if the money had been more important to me than playing out the experiment properly and finding out what would really have happened, I wouldn't have signed up in the first place. As it turned out, I didn't have spare mental capacity during the experiment for thinking about the money anyway; I was sufficiently immersed that if there'd been an earthquake, I'd probably have paused to integrate it into the scene before leaving the keyboard :-)
