It's actually interesting to consider the divergent paths followed by a merge scenario presented here. If we assume that uploaded-you is put through a simulated "going to university" experience, then it's a few years older than you are. Even if it was _only_ simulating classes and studying, somehow turning off any "human" needs for social interaction and enteratinment, it's had years of time to think new thoughts, assimilate new ideas, and become a fundamentally different person. If it's completely overwriting your brain's current state, then you're replacing yourself with someone similar to you but who'll be _obviously_ different to anyone who knows you. If it's more a merge scenario, then you're (effectively) killing yourself and the copy, and maybe the copy won't want to rejoin you if it means losing its own distinct state. Continuity of consciousness is weird to think about.
