People are material objects, but the materials out of which people are made don't matter. If your neurons were replaced by artifiicial ones that would function in the same way, would you not be the same person? You would answer any question in the same way as the original version of you would. I conclude that it is the computation that is performed by your brain that generates you. The materials don't matter. I could just as well generate you by a primitive analog computer. What matters is the computer program that is running on the machine, not the machine itself. If you believe that all possible universes exist (universes that can be generated by a computer program), then you ``always�� exist in some universe, because, by definition, you are a computer program. So, I would say that you will always find yourself alive somewhere. But it is interesting to consider only our universe and ignore quantum effects. Even then you will always find yourself alive somewhere, but you won't find yourself becoming infinitely old (see above). Because this is a classical continuation of you, it is much more likely than any quantum continuation that allows you to survive an atomic bomb exploding above your head. Saibal
