It is too late for the USA to cry over spilt milk. USA nuclear research and development, rocketry, cutting-edge semiconductor developments were all contributions by top-notch Chinese scientists in the past. Some may have come from Taiwan, but still also Chinese, like Morris Chang.
Most have now returned to mainland China, to teach and nurture younger Chinese scientists and engineers, in universities, research facilities and private enterprises like Huawei, SMIC, BYD, Alibaba, Tencent and others. There is no shortage of opportunities for them in China today. The sky is the limit.
When the USA talks about trying to lure these scientists back to the USA by making working environment safe and welcoming for them, I just could not stifle my laughter at their stupidity. First you chase them out with atrocious claims and punishments and now asking them to return is no more than a sick joke.
Moreover, China is building universities like no tomorrow and needs talents to staff critical departments. And these academics are well versed in the English Language, which is a bonus for China in its attempt to lure foreign students to study in China. What is now a growing stream of foreign students in Chinese universities is going to become a flood very soon. And that is going to be detrimental for Western universities charging sky high tuition fees that have become unaffordable even for USA students.
The fact that China now holds the greatest number of patents in science and technology is not lost on those scientists, engineers and academics still working in the USA. More will return, knowing that China is where the action and innovation is happening.
Perhaps the day will come when the USA might go ahead to accuse China of overcapacity in providing university education for the rest of the world. Never underestimate the mindset of the Hillbillies.
