While I don't see China becoming a hyperpower as many feared owing to its slowing economy, I also don't see China or the Chinese state 'collapsing'. Chinese state is remarkably stable for an authoritarian regime and China appears more stable right now than many democratic nations wrecked by populism (such as Italy). China will likely continue growing, albeit slowly and turn the world bipolar.
OF COURSE the communist dictatorship will either collapse as dictatorships eventually do, or the form of government will evolve into something else. Even our capitalist system will do the same; evolve or collapse, as we begin to run out of non renewable resources. THAT could throw a spanner in the works; a serious war over say oil is not out of the questions. Kuwait and Iraq where just appetisers.
My time scale is decades, even a century or a bit more.
This is my opinion based on observation and some reading. Spend a few minutes checking online, and you will find support for either China or India becoming the next superpower. For all I know, it could be both, or neither, although I suspect' neither' is a bit unrealistic..
Even Australia gets a mention because of our vast natural resources plus economic and political stability. I don't know how realistic an idea that is . I haven't really though of Australia in that way, and really don't care. I do think Australia will continue increasing its involvement with Asia, because we are geographically on the Pacific Rim. That especially means increasingly strong ties with China, over time.
I honestly don't know. You may well be right. Predicting future events is always tricky, so I'll sit on the fence I think.
Below is one of my favourite poems; "Ozymandias", by Percy Bysshe Shelley. I believe it refers to Ramses The Great
I met a traveller from an antique land
Who said: Two vast and trunkless legs of stone
Stand in the desert... near them, on the sand,
Half sunk, a shattered visage lies, whose frown,
And wrinkled lip, and sneer of cold command,
Tell that its sculptor well those passions read
Which yet survive, stamped on these lifeless things,
The hand that mocked them and the heart that fed;
And on the pedestal these words appear:
'My name is Ozymandias, king of kings;
Look on my works, ye Mighty, and despair!'
Nothing beside remains. Round the decay
Of that colossal wreck, boundless and bare
The lone and level sands stretch far away.
