Might just be me, but I don't think the world would be a better place with a separate caste of immortals controlling the world governments and resources.
Crazy, I know.
Crazy, I know.
How would I be able to enforce it? By somehow keeping the costs high? By lobbying?
Nothing would work, because this would be too big for the working class to just sit there and watch, and if lots of people get really pissed, it can turn very ugly, as history has taught.
People will want it and they'll get it, one way or the other.
So you might have doddering 120 year old ancients (potential predicted life extension) with ever more brain damage.
