> Yes, I would happily volunteer to be sterilized in exchange for living forever. In a heartbeat.
A world without kids and young people is a really, really sad state of affairs. I don't know and I don't care about what others would do, but I think I will just choose to end my own life rather than continue to live in such a dystopian future.
1. There wouldn't be zero kids and young people. Just not very many. The death rate will always be non-zero, and our ability to support new people will grow over time.
2. I get that no more children is a bummer, but I'm not really understanding how it is so awful that it could be described as "dystopian", much less something to kill yourself over. The world is vast and interesting, and children are just one neat facet of it.
In any case, I can see how it might work to give people a choice. If you'd rather die sooner and also have children, you could opt out of both the sterilization and the immortality.
