So you're saying that a dead 2 year old, who had already had half her brain removed and the other half was seriously damaged, and dunking that in liquid nitrogen with the hope that someday a new body could be built for her and she'd be perfectly normal again
I don't know how the fuck anyone falls for it. Really... Why would they think that even if their bodies were preserved that long, and the technology was invented to create what's missing, and repair all the damage done by the freezing process, that anyone would spend the 14 bazillion New Earth credits (or whatever currency there is in futureland) to bring some old fucker back?
In her case, the could have just saved a DNA sample. The story is clear about the condition her brain was in. Half was gone. The other half critically damaged.
I'd have to think that it would be questionable in futureland to resurrect a 20th century person, even if they were in pristine condition. Say 21 years old with much above average intelligence, who was taught everything that there is to know, with no medical issues, no trauma. Just frozen as-is without cellular damage. Why would anyone opt to wake them up? Just to ask "Hey, so what was life like in the 20th century?"
The whole cryogenics "industry" is a huge con.
If these people are religious in the least, they'd have to believe that the soul was trapped in that frozen body until it was awakened. If it wasn't, there would be no reason to reincarnate them. What if they picked the wrong part to freeze? Like, if the soul was really in the liver, or maybe in the spinal cord between C1 and C3. Oops, sorry, we cut that part off.
And if they aren't religious in the least, why bother? So they can wake up as a curiosity in the future? "Hi Cro-Magnon. Fire hot. We have spoken languages you don't understand. And try to wrap your mind around these three seashells. No more poison ivy toilet paper for you. No, don't hit females with a club to make them your mate/slave."
