Chinese language has its limits. Still Chinese the language is sophisticated enough to handle modern society, as you can translate verything from English to Chinese, sometimes with lots of work.
In comparsion, Chinese culture has bigger problems. I think the core belief of Chinese culture is social darwinism -- fittest survive and every man for himself. It is more suited for a pre-civilized society and that is why China is having a hard time connected to the rest of the world.
The day Chinese start to practice what Confucius said 2000 years ago"treat people the way you want to be treated", I consider that day Chinese finally come out of stone age.
