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.

These aren’t companies doing the patient storage. It is non profits setup and run by people who are signed up themselves.

Wasn't OpenAI a non-profit?
