"But can paradise exist with an growing population?"
I seriously doubt if we will have a growing population in the future.
A. if we can create wealth - then, historically, people slow breeding right down - to levels which give a population drop.
B. Robotic partners -- coming ready or not - and, my thought is that robotic partners will be the way preferred choice
and, with robotic partners - men, most certainly will not have babies --------- women still might - but, they will have limited numbers --------- AND, they might have robotic babies as well.
Either way - there should be a massive drop in breeding.
The key is for people to be able to have material without income from labour.
