One thing I would like to be mentioned is why these methods might work.
Assume the best possible scanning method is used, such that the future reanimators have a map of where every atom was bonded in your brain.
There’s going to be frost damage, even if cryoprotectant is used—there will be areas it didn’t reach, cracks from low temperature stresses, oxidation damage from time spent in the cryostat, and so on.
Future software could computationally reverse many of these damaging events—but there will be uncertainty in that there would be multiple solutions possible as to the “original” state. A video of the freezing process would allow you to calibrate the model used to computationally reverse the damage better.
Furthermore, this level of technology means it is probable that the reanimators would be able to “read” memories at some level of fidelity. If there are surviving notes about your life, they could potentially resolve ambiguities when there are multiple possible past memory states.
One thing that bothers me about this proposal is that the “reanimators” would have to be beings smarter than you ever were, and they would probably need to use more computational capacity to revive just one person than that person performed in their entire lifetime.
