China might build their own products and I can see them building WhatsApp alternatives, but I won't install Chinese alternatives to WhatsApp on my phone, which means the Chinese won't be able to talk with me, an European, all the while I'm communicating without issues with acquaintances from all over Europe and the U.S.

This means that the Chinese are living in a bubble. This isn't news of course.

But the other issue is that they can't attract much foreign talent to relocate there, like Europe and the U.S. have historically done. Because they don't have a culture friendly to immigrants, but also because their environment is toxic for those of us that are accustomed to liberal democracies.

And their "copy machines" are actually racing against the clock, as more and more factories get fully automated and thus relocated home, not to mention their rising middle class, thus their cheap labor advantage will eventually go away. So when multinational companies will no longer assemble their products in China, what will they copy?

Of course, their middle class are now sending their children to western schools and many of them will probably go back to China, but on the other hand the best and brightest end up having the choice to stay in the west and many of them will.
