I read the above comic, something which turned out to be a mistake because I have just enough understanding of physics, and philosophy to follow its line of reasoning, but not anywhere near enough to say if the scenario that presents for sleep, and survival of the self through the unconscious part of it is true, or just a thought experiment, and theory.
After having read it, I have some very rough nights, with the concept that if I fall asleep I die making it hard to fall asleep.
I understand that the creator of the comic is not arguing that falling asleep or losing ones stream of consciousness, but as I cannot imagine surviving the transporter, I suddenly find myself unsure if I can survive periods of unconsciousness.
Is unconsciousness during sleep something that a person should realistically fear? Obviously the body itself survives, as do the memories with one waking up -feeling- they are the same self that fell asleep. They will qualitatively be the same, but so too would the person emerging form a transponder. I am interested in if the person that wakes up is not just qualitatively similar, but numerically the same person that falls asleep? The survival of someone like me is irrelevant where this is concerned. My survival is what I am concerned about. As I imagine most other people are too.
On level of intuition, for me survival of both the body, brain, and memories seems important, but I dont know if they actually are.
Cheers! Thanks in advance for any help you can offer.
