Doctors' estimates of the feasibility of preserving the dying for future revival

When it comes to cryopreservation the thing I find infeasible is the idea a provider would bother with the preservation, under the incentives of capitalism.

If someone pays millions of dollars to a company that promises to freeze their corpse for 200 years, the company can simply freeze the corpse for a decade or two, take the millions of dollars as dividends and executive bonuses, then declare bankruptcy. The dead can't sue.

There's a news story about such a company where they basically throw the bodies in a chest freezer, or stuffed many of them together in one unit, etc. Nightmare fuel...

I have doubts that such a company could keep the power on for the next 200 years, with an increasingly unstable planet (climatically and politically).

Maybe sending your body in a lead coffin into the coldness of space is a better preservation method, maybe that's why the loser billionaires are so interested in going to space..
