Have you seen Paul's latest post yet? It seems much more well formed than his previous posts on the subject.
I left a comment there, but it's still under moderation, so I'll copy it here.
This seems like a problematic part of the argument. The reason we think torturing humans would be bad according to U is that we have an informal model of humans in our mind, and we know that U is actually a simulation of something that contains a human. Our “suspicion” does not come from studying U as a mathematical object, which is presumably all that a U-maximizer would do, since all it has is a formal definition of U and not our informal knowledge of it.
I agree, though it doesn't go as far afield as many of the other posts. It's actually another plausible winning scenario that I forgot about in the recent discussions: implement WBE via AGI (as opposed to normal engineering route, thus winning the WBE race), and then solve the remaining problems from within. Might be possible to implement when the FAI puzzle is not yet solved completely.
