Comment on Another attempt to explain UDT

I don't have a proper response for you, but this came from thinking about your comments and you may be interested in it.

At the moment, I can't wrap my head around what it actually means to do math with UDT. If it's truly updateless, then it's worthless because a decision theory that ignores evidence is terrible. If it updates in a bizarre fashion, I'm not sure how that's different from updating normally. It seems like UDT is designed specifically to do well on these sorts of problems, but I think that's a horrible criterion (as explained in the linked post), and I don't see it behaving differently from simple second-order game theory. It's different from first-order game theory, but that's not its competitor.
