Cryopreservation only matters if revival is possible. You can't just hand-wave this part and say "future technology will figure it out." This topic pushes you to think concretely about what revival would actually require: the level of technology needed, the types of damage that must be reversed, and the plausible mechanisms that could work. By engaging with the technical requirements and timeline uncertainties, you develop realistic expectations about when revival might become feasible and what conditions need to hold for success. The uncertainty is real, but it's constrained uncertainty you can reason about.
