> Population stagnation could potentially lead to worldwide cultural stagnation, which would result in humans never getting off the planet and eventually getting wiped out somehow. I understand the population piece, but I don't understand the cultural piece. Japan has stagnated, and it's clearly culturally vibrant. On the other hand, the United States brings in immigrants and is growing, yet I'm constantly scolded and reminded that I have no culture since I'm just a white person. Oh, and back to the population piece. We're approaching 8 billion. How do you feel about, say, 3-4 billion? I mean, it seems like that's a pretty good number of people to get things done. We'd have less people doing menial work (or not working) and we'd have more essential and necessary work, wouldn't we?
