Will cryonics ever work?

[The world will shine with light in our nightmare]

Watching this video got me curious if cryogenics, which is obviously something science hasn't advanced towards yet, is something that is even possible due to the physical effect that very low temperatures have on the human body; up to 60% of the body is water, which would of course be crystalized in the freezing process. Supposing that some rich, living person (putting aside whether they're dead to begin with) wished to be cryonically frozen (the Walt Disney thing is a myth, by the way), all of that water would naturally expand and that, along with necrosis, would kill the body in short order.

Unless cryonics were to advance in such a way to prevent the expansion of water and permanently conserve a person's skin cells, the concept is impossible and the cryonics 'industry' is a scam based purely on science fiction rather than science.

Might it ever be a realistic possibility for people to freeze themselves in a way without destroying their bodies beyond all use, or is it pure fantasy because the laws of nature fundamentally prohibit living things from being frozen for an extended period of time?

With current medical technology, no. In the future, maybe. The basic premise of cryonics as currently established is that we don't currently have the medical technology to revive these people, but we're gambling on the possibility that we will obtain such medical technology in the future because we just don't know what future medical technology will be like & what its capabilities will be. Developments in cryonics right now are focused on trying to limit cellular damage & preserve as many living-tissue features as possible in order to make it easier for the possibility that said damage can be reversed in the future, thus potentially allowing the subject to be revived. For instance, vitrification has now replaced mere freezing in order to limit damaging ice-crystal growth, because if you freeze fast-enough, then ice crystals won't have enough time to grow large enough to pierce the cell walls. Ensuring less damage now as a result of better-&-better cryopreservation techniques as they evolve may make it easier, if not likely for one who undergoes the process to be revived in the future.

No.

The expansion factors of water between solid and liquid causes catastrophic damage to all cellular features, membranes, nuclei, mitochondrion, DNA.

The only way you could do it is using a 3D atomic photocopier.

Seems more likely our rich folk (at first, it will work it's way down to everyone in time, just like A/C, color TV and disc brakes) will be staying alive indefinitely using various life extending technologies.
