So will China, but in a good way as research the US funded heads to mainland China. Xi must be dancing for joy, in maybe 10 to 20 years, China will be by far a big economic powerhouse, eclipsing the US on its way to the top. Funny thing is, the US is doing this all on its own.
This seems to me a repeat of 1930s Germany, where many scientists left Nazi Germany for the US. That turned the US into an R&D powerhouse. By then, no one will care what the US does, it will be totally ignored.
