One thing I'm asking myself concerning the concept of immortality trough a digital copy and especially the idea of a backup. A digital copy that exists while the body lives on is how consciousness is dealt with. Where would ones perceived self be present. Would that be copied? Would that copy not become another person. Could the copy of me and a new upload merge?

If I backed up myself trough an upload and then died in an accident. What would happen to my perceived consciousness?

I realize these are all hypothetical speculations over a sci-fi novel. But isn't that why we read sci-fi in the first place?

Anyway, would be curious to hear your thoughts on this dilemma?
