Still a copy though. Not a continuation of consciousness.
That said, every time a human goes to sleep, the brain re-organizes itself. It *could* be argued that the person we are *now* dies when we lose consciousness and a new person with the same basic programming boots up and lives a 16 hour life the next day, before it all happens again.*
But that's not an argument I'm hearing from Hickman. It's just 'copies of people treated as if they were the same people,' for reasons.
What does happen if they end up with two copies of someone? (Like Vulcan.) Do they kill one? Which one? (In Vulcan's case, the crazyevil one, who is the original? Or the reasonably well-adjusted copy?) Do these copies have souls? Do they have *the same* souls, or different ones? Is there going to be some weird metaphysical consequence of A) them not having souls, or B) them creating new souls and somehow creating some sort of imbalance that affects (overjoys?) soul-predators like Mephisto and Hela, etc. ("Yess! Make more souls! Er, I mean, mutants. Whatever." -Mephisto)
*Edit: I should add that I *like* that these heady concepts are being poked at, and do not feel bad that an explanation hasn't all been spoon-fed to be me in the first month. It's cool, and I'm here for the ride. There are a lot of writers that I wouldn't trust to have even thought of this stuff, and would be worried about huge plot holes or whatever (like Bendis, who drops ideas like grenades on his way out the door, and then does not a ****ing thing with them), but so far Hickman has a better rate of follow-through and isn't prone to just leaving a mess for the next writer to (probably) pretend never happened and ignore.
