Will it be a fundamental crisis for philosophy and theology? Or will we need them more than ever? Indefinite longevity will surely be bad for love. I promised to love you for eternity, but I really meant fifty years tops. But mabye love means, first of all, love of self. Living for an indefinitely long time would, presumably, be good for that. I can’t love myself if not I’m not around to love and be loved. Darwinian Larry, not without reason, doubts indefinite longevity is possible. We’ll never be able to control all the ways (evolutionary) nature is out to kill each one of us for the good of the species.
