From my book Singularity Rising:
Communist dictator Joseph Stalin maintained power through killing millions of his countrymen and terrorizing the rest. He often lashed out at his old comrades, sometimes killing them and their families; other times he was satisfied with just jailing their wives. Stalin, who was denounced shortly after his death by his successor Nikita Khrushchev, must have known how hated he was. But the dictator knew that those who hated him were too weak or fearful to hurt him.
The first cryonics patient was preserved in 1967, fourteen years after Stalin’s death. But what if, I wonder, cryonics existed during the time of Stalin, and the dictator hoped to have himself preserved? Stalin was too smart to think his successors would have ever wanted him back. So if, at the beginning of his rule, Stalin had hoped to someday use cryonics, he would have had to be a less ruthless ruler. To have any hope at cryogenic revival, the world will need to want you back. So if the world’s leaders intend to use cryonics, they will have to care more about what the future will think of them.
Stalin was almost universally loved and worshiped among the not-yet-jailed population. [EDIT: "almost universally" is stronger than necessary to make might point. The real numbers are not known and hard to come by. "A majority" would probably be a safe estimate.] But you do have a point that after his death it could have unraveled, though not necessarily so. Mao is still venerated in China, and Kim Il Sung in NK. Besides, narcissists are skilled in convincing themselves that everyone loves them, except for bad people. So I don't think your argument that
Stalin had hoped to someday use cryonics, he would have had to be a less ruthless ruler.
has no basis in fact.
This month's media thread includes a short article on some people's idea to have Ayn Rand frozen, which ultimately didn't happen. My first reaction was a shudder. I thought, I definitely wouldn't want Ayn Rand preserved forever. My second thought was, What right do I have to say who can and who can't get frozen?
Whatever your thoughts on Ayn Rand, I think this can spark an interesting conversation: What, if anything, should humankind do about people who are widely seen as harmful for the whole? For example, if the Castro dynasty in Cuba or the Kim dynasty in North Korea decide to freeze themselves to ensure they will continue oppressing their countries forever, should that be prevented? (And yes, my opinion of Ayn Rand is such that these examples came to mind.)
