I don't think I understand this post.

My claim is that it is easier to write down some stable utility functions than others. This is intimately related to the OP, because I am claiming as a virtue of my approach to boxing that it leaves us with the problem of getting an AI to follow essentially any utility function consistently. I am not purporting to solve that problem here, just making the claim that it is obviously no harder and almost obviously strictly easier than friendliness.
