Thanks for the link, that was interesting to read.
They link to a “medical report” from one of the cryprofreeze companies, about three people who were transferred from being frozen completely to just having their heads preserved (apparently this is a thing).
It contains such gems as describing said process of decapitating a corpse like this:
The patient was removed to an isolation tent with specially constructed supports, where a rapid conversion to neuropreservation was done using a high speed electric chain saw.
They go into some detaile about how the bodies reacted to being frozen for years and then warmed up again, which is interesting to read (for me at least) and shows that the technology needed to revive these souls is a long long time away (if at all)"
The only real hurdle in the revival process is the fact that we don’t know how to freeze folks while preventing microcellular crystals from forming. Reviving folks after that would simply be a matter of reversing the process.
Isn’t the real hurdle that the human body is composed of different materials that have different thermal expansion coefficients, meaning any kind of freezing or thawing will lead to cracks at all scales, even down to the molecular one?
Yeah, humans are large and it’s hard to freeze the entire thing at the same time even with very cold storage. The outside of you freezes before the inside and that’s problematic.
Smaller mammals like rodents have been frozen and thawed successfully while still living but they are way smaller.

And finding a way to reverse brain death.

Can we just make smaller humans? Would creating a homo floriensis just to send them on distant stars be a unethical?
Let’s do it and they can ponder our choices when they arrive long after our death.
Wtf!? Just going to casually drop that in there?
Yeah, some caveats apply but https://en.wikipedia.org/wiki/Cryopreservation?wprov=sfla1
