Other countries have had 20 times the population of America for centuries and yet pre H1b America invented all modern computing, the internet, etc etc as we know it. Not worried about other countries AT ALL.
Europe didn't do as much of inventing modern computing (though Bletchley Park would like a word) because it was still trying to recover from the destruction of WWII, and that set them back a decade. China and India didn't, because they were more than a decade behind. Having 20 times the population doesn't mean you're at the cutting edge.
