For whatever it's worth, despite never formally studying Chinese, I managed to read both the Chinese sentences, albeit with the wrong tones. Like to be fair I have studied Japanese, and I am generally a bit of a weirdo with a knack for this sort of thing — but I do still have to wonder if more people are just going to start casually picking up hanzi just from exposure like I have, as China becomes more prominent. I could certainly see it happening.
"China is the future" is a bit of a vague question, though. Just from my interpretation of it...
I absolutely think that the USA is currently crumbling as the world's hegemon — interestingly enough, the USA's flag actually has stars on it to represent a "new constellation", using the constellations in the sky as an allegory for the rise and fall of nations; so it indeed seems like the fifty-star constellation is beginning to fall beyond the horizon, as a new five-star constellation rises.
This being said, I don't think China's behavior as future hegemon will be the same as the USA's current behavior as present hegemon. I don't necessarily know what to expect from the future, though, so it's probably best to prepare for all possibilities until we gain a clearer understanding of the situation.
As soon as you are on top, your behaviour might change.
It might, it might not. America's behavior didn't change; from the start they've been aggressive and expansionist, the scope just grew as they became more powerful.
China's been growing rapidly for decades while very seldomly acting militarily outside their borders. They don't seem to have expansionist goals outside those declared over 70 years ago (ie Taiwan) and have even negotiated down on border conflicts. It's not impossible but it'd be strange for China to make a complete about-turn on their stated policy of non-intervention.
