North america is still the most innovative place in the world, and the most creative minds remain to be america-grown, from IT world to Hollywood. I think "好奇心和對未知世界的渴望" can be a motivating factor for large scale migration, but it is not the main one. The main factor for migration is the opportunity, or the lack of it. Most of chinese move out of China because they believe they have a better chance to succeed elsewhere.
I personally think the intense presure for survial in a foreign land is a killer for creativity, which prevents many new immigrants from taking chances and becoming real innovators. As a result, it is a tremendous waste of the talents among the Chinese immgrants.
It is even a bigger lost for China, because immgrants are still the risk takers by comparison and are the type of people that make the real impact in the world. In that sense, we should all be proud of what we have tried, especially thoes who started with absoulte nothing but a desire.
