Yeah, that response didn't have much content, but I think that's pretty understandable considering that by that point in their debate, Moldbug had already revealed himself to be motivated by something other than rational objections to Hanson's ideas, and basically immune to evidence. In their video debate it became very clear that Moldbug's strategy was simply to hold Hanson's ideas to an impossibly high standard of evidence, hold his own ideas to an incredibly low standard of evidence, and then declare victory.

So I can understand why Hanson might not have thought it was worth investing a lot more time in responding point by point.
