    Are there any even half plausible ways cryogenics might work with the technology we have? I mean, if they’re frozen their cells are ruptured.

        But whole humans are too big to quickfreeze. The cold just doesn’t travel fast enough through the torso and brain to not cause damage.

        Ok, there’s maybe a workaround. There was some news years ago, about someone that replaced a pigs blood with cold saltwater + glucose to keep them in a stasis and then just pumped the blood back to revive them. That aparently worked up to a few weeks but if you find something that keeps liquid at -100°C or less (and isn’t poisonous)…

          Yeah I won’t pretend to know or care about the way it’s done for whole humans. I am dubious of its feasibility, leaning strongly towards thinking it’s just plain old exploitation of grieving people.
