That entirely depends on what technology we develop. Water isn’t actually consumed in almost anything we do, and sunlight and heat-exchange with the earth provide an immense amount of energy if we capture them. The natural world is probably the hardest part. If we were okay with a crapsack world where everyone was just eating algaeic gloop and stuff the limit would be absolutely gigantic.

That’s very far from where we are, though. I’m just pointing out if you’re going to take her to task for inaccuracy, then accuracy is a nice thing to have. The problem is that we are not acting in a sustainable manner, nor even attempting to get to a sustainable state. The larger the population, the more difficult the challenge it is to be sustainable.
