Why do you need to make leaps to the future to find evidence for your claims? Anyone can simply look at the past 500 years and come to the opposite conclusion.

There's also not much evidence China will "eclipse" the United States (whatever that means). I hitchhiked mainland China in 2019 after studying the language in university precisely because I thought the country might "eclipse" mine.

I came back with the exact opposite conclusion.

If the definition of "eclipse" is more global cultural influence, I would challenge you to compare the number of American movies you've watched in the past year vs Chinese movies. Movies are just 1 dimension of this dynamic.

The country has simply too much history and insularity to propagate its influence throughout the world. The language is another key example- very few learn Chinese as a second language. Even the Chinese youth themselves often use the latin alphabet to write their own language on a keyboard.
