First, let's see some real movement on anti aging. AI can play go and drive cars, what'the anti aging equivalent.
2nd, we've already added those 20 years of average life in most places, without much anti aging. Antibiotics, sterile surgery, vaccination, geriatric medicine. Childhood deaths went down a lot. Mid life deaths too. Old age is much longer than it was with life expectancy at retirement trending towards 90.
We've already had the economic/societal consequences in the west/north/rich places. The first (childhood survival) too in the form of population explosions still in play in some places.
I doubt anti aging has bigger effects than that within the next 50 years, even if life expectancy at birth leaps to 100 tomorrow. Anyway if it really slows aging it'll extend people's productive middle life, which is mostly good economically.
