You know I love the idea of cryostasis, and the idea of reanimating people after death is great.
But why the fuck would future humans bother bringing all these people back, even if they could? Even if they have a utopian society free of scarcity and inequality, they would be bringing back mostly rich people who lived in a super different and bad time and have literally nothing positive to contribute to the utopian future, since they were a large part of the problems of today in the first place. Plus the vast majority of them are almost certainly elitist assholes who nobody in a utopia would want to be around.
Maybe it would be a humanitarian thing, but if these people are dead and frozen there’s no real imperative to do this to end suffering or something. Or I guess maybe bringing them back to try and figure out what the hell their damage is that they felt ruining everything was a better option than working toward the betterment of all.. but they’d only need a few brains in vats for that, no bodies, so sucks to suck, cryofolks.
If future humans don’t have a utopian society, the only real use for people from so long ago that I can come up with would be research subjects or slaves. And frankly there are easier ways to go about getting those..
So I see no possible future where people who cryopreserve get brought back en masse. Even if it’s entirely possible to surmount the technical hurdles.
