Well, we can do this for lots of specific cases. E.g. last time I spoke to Peter Norvig, he said his reason for not thinking much about AI risk at this point (despite including a discussion of it in his AI textbook) was that he's fairly confident AI is hundreds of years away. Unfortunately, I didn't have time to walk him through the points of When Will AI Be Created? to see exactly why we disagreed on this point.

This will all be a lot easier when Bostrom's Superintelligence book comes out next year, so that experts can reply to the basic theses of our view when they are organized neatly in one place and explained in some detail with proper references and so on.
