Who deserves to live? Ideally the brilliant, well-bodied, distinct and talented, varied in craft in hobby and humor, wit, literacy, mathmeatics, etc.
Who GETS to lives? Everyone. Once we do this (very certainly in the short future) we'll be able to travel to places like the moon, mars, etc. We'll be able to afford small colonies--once a person lives past the age of I don't know eighty? Helping one another and coexisting peacefully and with love will be EXTREMELY common-place: Even those psychopathic--that is, physiologically incapable of experiencing emotion, will in the beginning, either be paid a great deal of money, from a very early age, With their Consent, to act prosocially. Once this is a thing there will be no error in this function. The kepler exoplanets stand as a reality.
Science will develop more quickly; everyone will be a published author, programmer, scientist, all-around great-person. And everyone will want to have sex with everyone and anyone. There will be planets made to look and feel like this new Mad Max movie-planets to look and feel like bioshock, the time traveler, water-world, hell in the new american bible, hell in the old chistian bibles in the Beinecke library, hell like in the TORAH! There will be worlds with big mushrooms like in the original Willy Wonka, and ones where plants are made of LSD.
There is a whole lot out there--a whole f*cking lot. And I am DAMN WELL gonna be there for it. Hell, if chopping off my head and working on putting it to someone elses body doesn't work... I can always rely on my fellow human-beings :-)
