It occurs to me that there could be an ambiguity here, as it is indeed the case that, whereas there is only one first-person prior to the duplication, there will be two afterwards. Hence, as Chalmers says, there will indeed be a first-person in both cities. Both will be in a position to lay claim to the same antecedent memories, but one would expect their experience to diverge after duplication based on their individual locations. Does Chalmers rather claim some sort of ongoing superimposition of experience after duplication? If so, on what basis? Or is it possible that there was indeed some ambiguity of expression here? The whole issue of "where will I find myself" after duplication is in any case very curious. Deciding "who I am" and "where I am" can only be post-hoc on the basis of present experience in the context of memory. Were I in fact to make a prior bet on where "I" might find myself to be post-duplication, presumably of the two first persons who would eventuate, one would remember predicting correctly his destination, and the other incorrectly. The question then of why "I" might discover myself to be in the position of one of these first persons and not the other then seems to collapse into the general form "why of all possibilities do I find myself to be occupying this particular observer moment?". Fortunately under ordinary circumstances the issue of two identical three-persons being in a position to lay claim to the same antecedent first-person memories does not generally arise, but the problem seems to be the same even without this.
