If the machine intelligence revolution goes well, the resulting superintelligence could almost certainly devise means to indefinitely prolong the lives of the then still-existing humans, not only keeping them alive but restoring them to health and youthful vigor, and enhancing their capacities well beyond what we currently think of as the human range; or helping them shuffle off their mortal coils altogether by uploading their minds to a digital substrate and endowing their liberated spirits with exquisitely good-feeling virtual embodiments.
Immortality. Yay.
