There exists an observer moment representing you at N seconds, at N + 4
seconds and at all possible other states. They all ''just exist'' in the
plenitude, as Stathis wrote. The OM  representing you at N + 4 has the
memory of being the OM at N.


This I find confusing. How is there memory associated with an obserever moment? Is it equivocation on "memory"? As an experience, remembering something takes much longer than what I would call "a moment". It may involve a sequence images, words, and emotions. Of course in a materialist model of the world the memories are coded in the physical configuration of your brain, even when not being experienced; but an analysis that takes OM's as fundamental can't refer to that kind of memories.

It is true that human cognition, memories etc. are not instantaneous. There are two ways to keep the OM concept useful despite this. One is to extend each "moment" so that it encompasses, for example, the minimum period of awareness (probably a substantial fraction of a second), or any interval of arbitrary length, such as the waking hours of a day. This still allows one to think about questions involving continuity of personal identity where multiple copies or near-copies of a given mind are running simultaneously, the interval of the OMs under consideration being tailored to the particular situation. The other way is to bite the bullet and allow instantaneous part-cognitions. A memory is then only associated with an OM during the act of remembering, and each instantaneous OM covers only an instant of that act, in the same way a frame in a film covers only an instant of the action depicted by the series of frames.
