in the case of a copying machine I would experience an equal subjective probability of coming out as the original or the copy
If you have a copying machine that is capable of outputting more than one (identical) copy, and you do the following:
first, copy yourself once
then, immediately afterwards, take that copy and copy it 9 times (for a total of 1 original and 10 copies)
Do you then expect a uniform 9.09% subjective probability of “coming out” of this process as any of the original + copies, or a 50% chance of coming out as the original and a 5% chance of coming out as any given copy?
If it’s immediate enough that all the copies end up indistinguishable, with the same memories of the copying process, then uniform, otherwise not uniform.
