Louie, there appears to be a significant divergence between our models of AI's power curve; my model puts p=.3 on the AI's intelligence falling somewhere in or below the human range, and p=.6 on that sort of AI having to work on a tight deadline before humans kill it. In that case, improvements on the margin can make a difference. It's not nearly as good as preventing a UFAI from existing or preventing it from getting Internet access, but I believe later defenses can be built with resources that do not funge.
