Aubrey has promoted that the accumulation of seven types of damage of living are the cause of aging. If we fix the damage of aging extremely well damage then like repairing a car we can massively extend lifespan.
As usual many interesting insights. In the 30-40 minute part of the interview, Aubrey points out the downside of herd mentality for researchers. If many researchers compete in certain fashionable and high profile fields, then they minimize their contribution. They beat some others by days or weeks, instead of making a breakthrough that would otherwise not occur for decades.
This explains some of the importance of Elon Musk. The breakthroughs in space or electric cars might not have happened for many decades without Elon creating SpaceX or Tesla.
Around the 50 minute mark, Aubrey answers the question about how we can fix the environment and increase the carrying capacity of the earth.
Global aquaculture increased 527% from 1990-2018. We eat more farmed fish than wild fish.
We will still only get older one year at a time. Impossible to have 200-year-old people before 2100. Impossible to have 300-year-old people before 2200.
At about one hour, Aubrey talks his expectation within 3-5 years there will be a rapid shift in public expectation in longevity. The lab and clinical research will get to the point that experts will be willing to say radical longevity is achievable. Major media will then trumpet it. The public will then change their beliefs.
