just to outline this fictitious would you rather, you rich enough to retire cryogenic preservation is perfect. you could live out the rest of your life in retirement and see the world evolve “like god intended”, or you can adopt cryogenic lifestyle where you freeze yourself for however long you want and stay thawed for however long you want but your still a human with natural human lifespan so you will eventually die.
of course contingencies are allowed if you think something cataclysmic will happened you can be dethawed abruptly and considering future medicines to extend your lifespan is allowed
none of that shit works and won’t work for a good minute, cryonics is rapture for nerds that take scifi way too seriously
what we already know tho is that because there’s one payment to store meat popsicle effectively forever and this shit is ran by true believer techbros, it tends to run out of money pretty regularly. that means they run out of liquid nitrogen and meat popsicles thaw, and this already happened more than once
