Hanson has made a lot of comments recently about how intellligence is poorly defined and how we don't really know what it is - e.g. 77:30 and 83:00 minutes in. I think we do now have a pretty good idea about that - thanks to the Hutter/Legg work on universal intelligence. If Hanson was more familiar with this sort of material, I rather doubt he would say the kinds of things he is currently saying.
