And there is also the downside risk even if it does work—what if you are reanimated to be a slave of some non-FAI warlord! From this example, we can see that the probability of successful cryo actually resulting in a negative outcome is at least as big as the probability of non-FAI winning out.*
So the question actually reduces to a classic heaven-and-hell or nothing argument—would you rather the chance of heaven with the possibility of hell, or neither?
(*Of course, if the non-FAI sees no need to even have you around and doesn’t even bother thawing you out and just kills you, this is a negative outcome also, as you’ve wasted lots of money.)
This is a blog devoted to rationality—it’s no wonder it hasn’t been linked here.
