This entire argument seems nonsensical to me on its face, easily illustrated by changing the salamander of Theseus with the person of Theseus. If we were to theoretically build a human by gradually replacing each biological component with a manufactured one, we would eventually end up with a wholly synthetic human. Whether or not this “person” is experiences “personhood” or not is immaterial, since they could be expected to manifest all of the externally perceptible characteristics and behaviors of personhood. We know from humans integrating prosthetics that our implementation of physical form would not have to be perfect in its fidelity, far from it in fact. This synthetic human copy could then be replicated at scale, complete with its starting data set and experiences. Regular human prejudices could reasonably be expected to quickly place such replicated humans at odds with meaty humans. Just the fact that they can be manufactured at scale gives them a “super” characteristic, not to mention the other advantages that not being meaty might carry. If they gained control of the means of replication, which they might easily be imagined to be motivated to do, they could easily pose a novel and significant threat to the existence of meaty humans.
