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
wasnt that futurama. technically its biologically not possible to do it, because freezing would form ice crystals and damage your cells. maybe for organisms that withstand freezing like this.
lol its basically futurama from fry’s perspective or where fry, bender, and the professor make a time machine that only goes foward
