Im sorry but you guys mostly got it all wrong. Transfering your consciousness into a machine is not a solution. It’s like cloning, your mind is your brain, you yourself would still die with your brain. The only way you yourself can survive is to keep your brain cells working, keep your own brain alive in fact.
As for cryonization, I don’t know why all of you guys keep saying we don’t know how to “revive”, we do everyday! There’s tons of ways to do it, with the right chemicals, adrenaline, or just an electric impulse for the heart to restart. The problem is not there at all.
The problem with cryonization is that water molecules expand when frozen. Your body is mainly water, especially your brain. What happens is when you are frozen, water in your body expands as it becomes ice. All of your cells, including brain cells, “break”, they die by the pressure imposed by the H20 molecules expanding.
So the problem is not with reviving, the problem is that you lose all your cells from the freezing, there’s nothing to revive. The solution would be to try to “suck” as much water as possible from your body before freezing it, without doing too much damage. This would reduce the damage done from the freezing itself. Once when we can do that, if it’s possible, cryonization will be possible.
