Just like the electricity is motivated towards structural activity according to its source of energy from which it can be considered also distinct,

the core-self is distinct to the sensory apparatus of the bodies both physical and subtle, but it provides the motivational fuel to remain a structurally cohesive organism, of the living entity as known.

Therefore since the possibility of machine consciousness exists and may become evidenced through AI under short notice, cryogenically frozen person bodies may be able to be revived, perhaps.

But then the atma would still be and have to remain separate, and may not partake to the live of new shell-person, who may have to operate a like an AI type of conscious “material”  entity body.

A total mishap! The environment will be gradually put to the service of cruder forms of existence, albeit materially advanced and intelligent, in terms of seeking to do the upmost with the energies afforded by material nature. 

It is more and more evident that life or humanity initially can be eliminated as a result of different reasons, some of those may be more subtle. We are not dinosaurs, they couldn’t kill themselves knowingly, we only need to choose the weapon. We can be our worst enemies, as a species.
