> We already get to live 2-3 times as long as our ancestors
Not really, at least those that survived long enough to become our ancestors. When you take childhood mortality out of the mix, the numbers don't look that different than our current life expectancy. The other thing pulling the curve down in previous eras is the high rate of death for women in childbirth.
If you dodged those bullets, and didn't get knocked on the head or cut down by a major epidemic, living into your 60s or 70s has pretty much always been possible.
