What I find confusing is that (from a quick skim) there's no mention on how easy it would be to actually bring back the brain in, say, 50 years. Does this method make reviving brain tissue easier?
Personally that seems more likely tha figuring out a new reversible freezing process.
Essentially it kills it (and kills it fast), then binds all proteins so they remain intact.
It's just a logical development. Less damage => more chance of recovery.
