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.
Well, you suggested to let them do it. I’m suggesting that they will not hesitate to commit massive human rights violating, nonconsensual nazi experiments, so no we shouldn’t allow them.
The fact that it absolutely won’t work is secondary.
