Elon Musk said that soon it will be possible to defeat aging: [Can you and I reverse aging? Will we catch it?] I haven't spent much time on the subject of aging. But I really believe this is a completely solvable problem. I think once we understand what causes aging, the answer will be incredibly clear. This is not some delicate process. I say this because almost all the cells in our body age at the same rate. In my life I have never seen a person with an old left hand and a young right hand. Why is this so? This means that there must be some kind of clock that synchronizes the work of all thirty-five trillion cells in your body. And you know, in death, by the way, there is also a certain benefit. There's a reason our lifespans aren't longer. If people live forever or for a very long time, I think there will be a risk of petrification of society: everything seems to freeze in place. Society can become inert and lose its vitality. But do I also think we will find ways to extend life and maybe even reverse aging? I think it is very likely.
