How exactly are you guys imagining that we support a population that lives forever? Earth’s population cannot grow exponentially indefinitely. Where do these people live, what do they do, where does their trash go?

It’s not clear whether humans can live on the moon long-term. The more likely solution is that we’ll need to heavily discourage people from having kids. Is that really more humane?

Well, maybe we should focus on expanding outside of the earth too? Population is growing anyways.

Also that seems like a way more rewarding way to spend life, than meaninglessness, risk-less human zoo, that some commenters are trying to sell, while bashing any project more ambitious than just keeping general population warm and cozy.
