In the grim dark future cryosleep or hypersleep or something similar will probably be used to extend peoples lives (and thus politicians careers) before it is ever used for space travel.

Give it time and you'll eventually have, through repeated extensions, term limits of one thousand years or even ten thousand, for congress/senate/president/etc.

You'll have CEOs and upper executives who have lived for 80k years dropping out of hypersleep once a century to document how the shoreline of north america changes near their beach home, as a sort of hobby.

Fart huffing professors (it's a professional sport in the year 28,841 AD) will come out of sleep once every millenia to track the evolution of something irrelevant, like gnat penises.

Big game hunters will wake up every 100k years to hunt new big game prey that just evolved--back into extinction. That and to check with their portfolio managers who will be AI or a highly evolved mongoloid goblin race of slave-quants.

I'm still working on the game btw. Anyone up for testing some prototypes when they're ready?
