I wonder if US still manages to keep the most promising?

Yes, but today less so than yesterday? We also are benefiting less from the top students with state funded undergraduate education in China and India.

On top of that, it is a significant reverse brain drain. Like 20-25 years ago you'd be hard pressed to find tenure track CS faculty at most America programs let alone a major program lime Cal or UIUC consider returning to a program like Shanghai Jiao Tong or IIT Bombay compared to today.

It has upskilled academia in those countries, but we also lost talent who could have remained here.
