China has gone from an undeveloped nation where people were literally starving to death by the tens of millions, to one of the most powerful and economically successful nations in the world. And they did this all in less than a single human lifetime. This trajectory of success is unlike anything we've seen anytime in human history excluding growth from military expansion. They're greatly outpacing the United States' rise from backwoods colonies to the most powerful nation in the world, and they've even exceeded reconstruction era Japan. If they can maintain even a fraction of their current momentum and trajectory, China is well on the path to becoming the most powerful nation in the world. And that role is implicitly accompanied by the privilege of being able to heavily influence the path of our entire world and, consequently, species.
So yes I think it's completely absurd to suggest they've achieved anything short of remarkable success with their system of development and governance. But the question is what will happen in the process of this success and whether the path they've taken is sustainable or not. Is their growth indeed on the current exponential it seems to be on? A sigmoid where this wildly exponential growth will start to level off, or perhaps even something like a bell curve where the rapid ascent will be met by a comparably rapid decline?
