How do people who sign up to cryonics, or want to sign up to cryonics, get over the fact that if they died, there would no-longer be a mind there to care about being revived at a later date? I don't know how much of it is morbid rationalisation on my part just because signing up to cryonics in the UK seems not quite as reliable/easy as in the US somehow, but it still seems like a real issue to me.
Obviously, when I'm awake, I enjoy life, and want to keep enjoying life. I make plans for tomorrow, and want to be alive tomorrow, despite the fact that in between, there will be a time (during sleep) where I will no-longer care about being alive tomorrow. But if I were killed in my sleep, at no point would I be upset - I would be unaware of it beforehand, and my mind would no-longer be active to care about anything afterwards.
I'm definitely confused about this. I think the central confusion is something like: why should I be willing to spend effort and money at time A to ensure I am alive at time C, when I know that I will not care at all about this at an intermediate time B?
I'm pretty sure I'd be willing to pay a certain amount of money every evening to lower some artificial probability of being killed while I slept. So why am I not similarly willing to pay a certain amount to increase the chance I will awaken from the Dreamless Sleep? Does anyone else think about this before signing up for cryonics?
Say you're undergoing surgery, and as part of this they use a kind of sedation where your mind completely stops. Not just stops getting input from the outside world, no brain activity whatsoever. Once you're sedated, is there any moral reason to finish the surgery?
Say we can run people on computers, we can start and stop them at any moment, but available power fluctuates. So we come up with a system where when power drops we pause some of the people, and restore them once there's power again. Once we've stopped someone, is there a moral reason to start them again?
My resolution to both of these cases is that I apparently care about people getting the experience of living. People dying matters in that they lose the potential for future enjoyment of living, their friends lose the enjoyment of their company, and expectation of death makes people enjoy life less. This makes death different from brain-stopping surgery, emulation pausing, and also cryonics.
(But I'm not signed up for cryonics because I don't think the information would be preserved.)
Thinking about it this way also makes me realise how weird it feels to have different preferences for myself as opposed to other people. It feels obvious to me that I would prefer to have other humans not cease to exist in the ways you described. And yet for myself, because of the lack of a personal utility function when I'm unconscious, it seems like the answer could be different - if I cease to exist, others might care, but I won't (at the time!).
Maybe one way to think about it more realistically is not to focus on what my preferences will be then (since I won't exist), but on what my preferences are now, and somehow extend that into the future regardless of the existence of a personal utility function at that future time...
Thanks for the help!
