My comment on that was here. To quote it in its entirity:

Um: yuck. For one thing, why is the agent assumed to be summing infinite sequences in its utility function in the first place?

My reaction these days is much the same. We can forget about most things after the universal heat death. So: this is a kind of fantasy mathematics. Best to ignore it - and focus instead on things that have some chance of being useful.

You're objecting to his 2009 paper, which is about a sum over infinite time. This 2007 paper is timeless.

My response to his 2009 paper is here. At present I think that it a) assumes what it is trying to prove, and b) assumes there is no time discounting, and so could be seen as an argument for time discounting. But I haven't looked at it closely enough to be confident of (a), given how accurate Peter typically is.
