I’ve been watching the TV series Pantheon and I really like it, but this tiny aspect is something I can’t quite grasp. So these people have their minds uploaded to the cloud - and they make a point to state that they’re still “them” - alive, real, authentic. But would it really be like that? The process is brain mapping, so essentially they just make a perfect clone of your brain/mind and run it digitally. But it’s still just a simulation. A perfect clone is still just a clone. The original person is gone. I don’t see the “continuity” aspect.
I think the show Severance covers this topic well even though the premise is slightly different, I believe the result would be the same. You have a fork of your existence basically since the self and its experiences are local to the entity of the particular snapshot and you’d grow and diverge. How much you diverge depends on the environment and stimuli you experience.
I’d hate to be the one in charge of

merging those forks.
