ELON MUSK: "It's important to appreciate that in most areas, China is very advanced in manufacturing. There's only a few areas where it is not. China is a manufacturing powerhouse. Maybe if you start getting to hundreds of millions of humanoid robots a year, I think you're going to be the most competitive country by far. We definitely can't win with just humans because China has four times our population. So we can't win on the human front. Our birth rate has been low for a long time. The US birth rate's been below replacement since roughly 1971. So we definitely can't win on the human front, but we might have a shot at the robot front."
