Sure, there's no question that the contents of our present memories may be stored. The question is what happens a billion years down the road, with a billion years worth of memories, at the increased clarity which will most likely be desired, with presumably a billion people (more?) drawing on the same resources. If we discount terminal entropy, and assume that there is a finite amount of matter in the universe, then there logically must be a point where all resources will have been consumed. Is there a way to avoid this? Will the universe experience heat death before then? Does this eliminate the possibility for "true" immortality?
