7 billion mofos on the planet and "eternal life desirable for society?".
U w0t m8?
I think it might even be possible eventually, but definitely not desirable IMHO. Fuck no.
You just indicated yourself that even without eternal life, overpopulation is/ is going to be an issue.Maybe if we know we are going to stay around forever, we'll actually have a strong incentive to figure out a solution for overpopulation.
Anyone not expecting life extension technology to become available in the future is being rather shortsighted.
Ask any old man, say Warren Buffet, if they could trade all their wealth for their youth they would in a heartbeat.
More interesting to me is simulating the human brain. Lots of great Scifi written on that.
