Well, depends on how much you discount the expected utility of cryonics due to Pascal’s Wager concerns. The variance of the payoff for freezing tissue certainly is much smaller, and freezing tissue really isn’t a big deal from a technical or even societal point of view, as evidenced by, say, female egg freezing for fertility preservation.
Sounds like a service that cryonics providers might usefully diversify into.
How long a shot it is that this is a useful thing to do, compared with cryonics?
