I don't think humanity will run into any capacity problems because of that, due to how grotesquely overpopulated it currently is. As far as I see it, every country in the world should be well below replacement rate, for the long run. Setting aside some problematic side effects stemming from our current social system setups. A small fraction of the current world population would probably enable everyone to have a much higher quality of life, if organised properly. We probably don't need to worry about who builds our cars when there are close to 10 billion of us. Where we'll get our food from, on the other hand -- I think that's where the real crisis lies.
