In short:
A live-stream broadcast of China’s military parade has captured Xi Jinping and Vladimir Putin discussing biotechnology’s potential to extend life.
An interpreter translating Mr Putin can be heard saying in Mandarin that human organ transplants could let “us live younger and younger, and perhaps even achieve immortality”.
Mr Xi responded that it may be possible for people to live to 150 years this century.
I honestly believe people could live to 150 within the next century and if organ transplants are part of it it will either be due to cloning or far better control of the immune system than we have now. I don’t expect those advances to be soon enough to help either of these guys, no matter how much money they have.
I would expect nothing or much more than 150. You only live as long as the weakest links in your body. Solving one isn’t going to get ypu to 150. And if you solve enpugh to get to 150, you should live a lot longer.
I wasn’t setting an upper limit. There is good evidence we are closing in on some of the causes of the symptoms of aging, as well as gaining evidence that dealing with the symptoms may reduce the effects of aging. If we only have those basic tools in the next 100 years, I could see lifespans being pushed to 150 to 200 for the typical person. If we can also deal with the lesser regenerative capability of the brain, I could see people living for centuries. As you said in other comments, there are a lot of interconnected pieces, and just fixing one or some of them won’t be as useful as fixing all of them, which really takes transplants off the table as a general solution, but also means we may see limited increases in life span rather than getting past the tipping point of life extension research outpacing the gain it gives you, eg., extending lifespans more than one year per year.
