Well, even presuming infinite computation it does not follow that any
particular subject would get an infinite slice in order to experience
infinite subjective time. Nor does it follow that you or I,
recognizably such, would resurrect even given this highly hypothetical
infinite computation due to an order of infinities issue. For you to
resurrect it would be necessary for all the supporting conditions for
you to exist, not just the atoms in your body, to spontaneously come
together in one locale in this infinite computational maelstrom. That
would also have to be the case for every other being that ever existed,
ever will exist or ever could exist in any possible configuration of a
universe since neither you nor a universe like ours are in no wise
special if the argument holds water.
Pretty thin hope for immortality and infinite personal vistas if you ask me.
