CronoDAS, I'm glad you brought up this issue. Sadly, I don't think there's good evidence that cryo, as practiced today, works. I think it is reasonable (but of course, not ideal) for people to dismiss things which are only theoretically possible but not practically possible.
If we had verifiably working cryo today, it might be easier to change people's minds.
Cryonics is being deeply confused with suspended animation in this thread. Cryonics has nothing to do with cellular viability. It's only about preserving the wiring and physical structure of the brain by any means necessary. In current cryonics, all cells are totally and completely dead long before the procedure is finished. But we also have electron micrographs showing very good structural preservation of these dead cells. The cryonics revival technology will need to manipulate trillions of atoms inside of each of billions of cells. No low tech is going to be able to revive them.
Thank you for clarifying this point.
FYI I was referring only to "Cryonics" when I said cryo in the parent comment, not to "suspended animation".
