As we move farther away it becomes harder to self-identify. I have some difficulty self-identifying with an upload but there's still a fair bit. I have a lot of trouble identifying with a beta copy. In fact, I imagine that an accurate beta version of me would spend a lot of time simply worrying about whether it is me. (Of course now putting that in writing means that out super friendly AI will likely only make a beta of me that does do that worrying is potentially counterproductive. There's a weird issue here where the more the beta is like me the more it will worry about this. So a beta that was just like me but didn't worry would certainly not be close enough in behavior for me to self-identify with it. So such worrying in a beta is evidence that I should make the self-identification with that beta.)
