Why DOESN'T that person's >QE continue. First, the burden of proof is on Thomas' side. If he claims that a duplicate or simulation constitutes a "continuation" of a person, how is that claim justified? It certainly doesn't comport with the ordinary use of language. As RBR has said, If you build another house from the same blueprint as an existing house, the second house is still a different house. If the first one is burnt down and then another is built, whether at the same location or not, and whether or not built with a used or aged aspect to resemble the old one, the second house is a new one, not a "continuation" of the first. (And the insurance company will pay off on the first one, unless it thinks the owner burnt it on purpose.) The new one may be "just as good" for many purposes, but it is still distinct. If you insist that mere similarity justifies calling a duplicate a continuer, then that is not an argument but only an assertion of preference with no real rationale that I can see. In math, as Thomas knows, a curve is "continuous" if (roughly speaking) whenever x changes by a very small amount, y or f(x) also changes by a very small amount. There are no gaps in the curve. People aren't curves on paper, but a similar principle seems to apply. You and your physical predecessors and successors are continuous if there are no gaps in your existence--only gradual changes. You share material, space, and time. If change is relatively rapid, then you are considerably different from your somewhat earlier selves and somewhat later selves, and there will be practical problems in deciding strategy, but that isn't news. At least there appears to be a viewpoint both reasonable and allowing room for optimism.
