How would you recommend responding?
I think I'd point out that he's a fairly public person, which both should increase trust and gives more material for ad hominem attacks. And once someone else has dragged the discussion down to a personal level, you might as well throw in appeals to authority with Elon Musk on AI risk, i.e. change the subject.
I'm giving a talk to the Boulder Future Salon in Boulder, Colorado in a few weeks on the Intelligence Explosion hypothesis. I've given it once before in Korea but I think the crowd I'm addressing will be more savvy than the last one (many of them have met Eliezer personally). It could end up being important, so I was wondering if anyone considers themselves especially capable of playing Devil's Advocate so I could shape up a bit before my talk? I'd like there to be no real surprises.
I'd be up for just messaging back and forth or skyping, whatever is convenient.
