For me it still doesn't make sense. Cryopreservation is legal and done only to dead people. Which means if they want to be alive again two problems need to be solved: 1) unfreeze with success, 2) resurrect. Both are non trivial for quite some years.

Is resurrection an actually difficult problem? My understanding is that merely restoring circulation to an otherwise-healthy brain should cause it to regain consciousness? Assuming the cryopreservation happened early enough before significant brain damage occurred (or was successfully repaired during the “unfreezing” process - which is currently the limiting factor) resurrection shouldn’t be a problem?

  The more people study the matter, the less of a boundary between `body` and `consciousness` exists. Our body, and all the pesky juices/hormones produced by it, and the stuff produced by bacteria in our digestive tract have direct impacts on what our mind perceives. Restoring circulation is insufficient.

  Is it not? Especially in this context. People who are cryogenically stored, died due some reason - old or trauma. We cannot resurrect old people; trauma medicine is hardcore and we can sustain and fix some people, but sometimes we cannot.

    I imagine it'll come down to the cause of death and the time-to-freeze. If you had a heart attack and it just wouldn't restart, that feels like a tractable problem in a world where we can do some crazy shit like 3d print you a new heart (making it up, please don't attack the 3d printing hearts idea, it's dumb). If you had some sort of trauma that put you into a coma, idk, I could imagine that some sort of futuristic stimulation could bring you back. Even now you can possibly live on your own without machinery, possibly even breathing on your own, your brain just isn't driving critical functions like feeding yourself. Today we have to let people die in that scenario, what if we could freeze them and in 100 years there's a way to trigger new brain activity? If you're shot in the head, obviously I'm going to be a lot more skeptical of the ability to bring you back.

Waiting quite some years isn't really a problem here.
