Here is a curious, but really debatable view on our population, that I've read somewhere. There are 60 billions people total, floating around and waiting for their turn to "manifest" and live. Such a life is very tiring, so humans need a lot of time to recharge: usually, 700-1200 years. Humans aren't created out of thin air or of proteins: bodies can be replicated quickly, but "creating" an actual human takes longer than the lifespan of an average solar system. With an average lifetime of 70 years, we can't have more than 10 billion "participants" living at the same time. We also can't just fix aging because even with a perfect body, life is very tiring.
