Earlier quoted context omitted.
It is not "supernatural shit", but it is Pascal's Wager. It takes the same form and has the same flaws. It is an invalid argument. By paying $25k to be frozen, you also get a nonzero chance that you'll be revived and live through thousands of years of torture.
Sure, thousands of years of torture are possible for you if you're a cryonicist -- but in such a world the same risk would apply to trillions of other sentients. If you aren't completely selfish, you're better off investing your energy in preventing such a world instead of trying to dodge the bullet personally.
How is getting your head frozen investing in preventing such a world? If you want to improve the future, maybe you should invest your $25K in humanitarian efforts instead of a desperate attempt at personal life extension.
