A VERY interesting post about cryopreservation.
"Cryonics is the morbid process of freezing rich, dead people who can’t accept the concept of death, in the hopes that people from the future will be able to bring them back to life."
Well, not that simple, actually :
- "rich people" : there are companies, today, already selling services of cryopreservation. It's not free, of course, but much cheaper than the lifetime cost of any "standard" addiction (cigarettes, alcohol, ...) that even "normal" (i.e. not "rich") people actually afford.
- "dead" : well, that's the subtle point. People are put in cryopreservation just before they are completely-definitely-forever dead. From the scientific (cryonic) point of view, the clinical death (heartbeat + breathing stopped) is not the end of the road (even though this defines "legal death"). Cryopreservation offers to put the body (or just the brain) in "pause" mode until the day science is able to revert it back to "life" (if this becomes ever possible). So, this is not at all about reviving dead people, but rather about interrupting their dying process until the day we can revert it. (But this comes with a lot of "if")
