Do you equate the Chinese to nazis? Because that's insane and totally fear-mongering, especially if you think China is evil but other countries would use scientific research for only rainbows and puppies.
As bad as the US is in many different ways, China is immeasurably worse. A future dominated by a hegemonic China would be a dark world. Little steps like these are helping to contribute to that possibility in 50-100 years.
Great powers historically have not usually been the largest countries population-wise. That would seem to indicate that there's no reason we should expect the inevitability of all else becoming equal.
No, I emphatically do not. That's the most false and inflammatory misreading of my comment possible. The Chinese people are not villains, full stop.
The point I was making is that political regimes matter when it comes to the desire for progress in science and technology, and the idea that it doesn't is naive. I'm glad the Nazis and the Soviets were technically and scientifically behind the Allies and the West, and I think the world would be better off they had stayed even further behind -- even if that meant that humanity as a whole has its scientific and technical progress retarded for the want of their contributions.
