Sure isn't.China, USA and Europe have been fighting for the top spot for years, nothing new there,+..
Now it's China's turn again.
The pattern is the same every time.
Country gets wealthier
Becomes a bully to sustain growth.
Invades resource-intensive neighbours or strategic countries by financial or military means.
Gets richer and no one wants to do menial tasks
Use invaded or imported cheap labour.
Everyone gets so lazy that everything is sourced externally
Neighbours get wealthier.
The country's government gets desperate and senile.
Civil unrest, increased unionism / socialism, widening gap between rich and poor.
Economic or military take over of the old ex lazy power country by a country that has benefitted from all of this.
Next countries turn.
It's been happening for at least 4,000 years and will keep happening.
The reality is that China has already taken over from the US, it's into phase 2 or 3 - bully and invading neighbours or strategic countries. Just like every single power before it.
In theory it's India's turn after China, but India couldn't organise a root in a brothel.
