Which population?

The situation in most well off countries is already that native populations have fallen below replacement rates. The result has not been to rejoice in the would-be crisis being averted but instead the crisis has been inverted and now those countries "need" to import foreigners to keep their economies from imploding. Or are you suggesting population control for africa and the middle east? Because I'm not sure they'll agree.

I agree that society needs to adapt to the post-scarcity reality but "population control" is and will always be something dystopian. It's also irrelevant because the more we automate the less people we actually "need" so no amount of population control will ever solve the underlying issue.
