So here’s my best bet of how you could make a digital upload actually be you. Say you could do a full biology simulation, and you use that to essentially extend your brain like extra layers of computation. Then you slowly turn off parts of your original brain while adding more chunks of functionality, until all of the original brain is gone. This would be you in the sense that there is a continuous chain of being between your original self and your digital self (counting sleeping and maybe coma as still part of that chain of being) Of course if this was enough to designate you still being you, it would throw into question if you stop your heart and then restart it, are you still you? (Probably the nature of stopping hearts is more complicated than I think it is, so I am not 100% sure this is a valid objection)
