What an interesting article. Perhaps Xu is not giving as much credit to the people as they deserve. I'm quite curious how he is deriving evidence for making such bold statements, considering the fact that he has spent quite a bit of his life in a lab. For him to say the best people in China have either left or retired is really sad. Although it's true that China has become commercialized and is a country under great control, I don't see how Xu has truly taken the time to explore the brilliance that current students and future students hold. As time progresses, even America has become very materialistic and commercialized, but that does not mean that the best that America has to hold has passed. It simply means that times are changing. Maybe it's because I am a teacher and have great faith that my job in teaching and helping to shape the future of our country will hold great promise for the future. Many of my Chinese students are very innovative thinkers, and their roots lie in China.
