He should measure that on proportion. China has way more people. So in that regard, the Russians are very good, in fact, probably the best, but they are constrained by their country and economy. The USA imports talent and uses that talent creatively in the economy. If we stop importing talent we are screwed. If we stop increasing our population size we are also basically screwed. China has a billion or so people to feed. They own global manufacturing. A push to robotics and AI based technologies will cause some major disruption to their internal economy.
