To even suggest China was united let alone centralized for that long is so blatantly ignorant I‘m not even going to talk about the lack of micromanaging capabilities of ancient governments. Old China was overthrown and China‘s government today has no resemblance whatsoever to old dynasties so it doesn‘t even make sense to bring them up as an example for Chinese ingenuity. Besides, the speed and process of how inventions were made thousands of years ago compared to today are on entirely different planes of existence.

The argument is not that autocratic states cannot be innovative under any circumstances, but historically, self proclaimed communist states had have their fair share of troubles with it because of stagnant hierarchies. Communist China is a very good example of a bad environment for innovation for reasons mentioned above.

The only Chinese innovation I can think of is the introduction of gamified hyper fast consumerism via Temu, Shein and TikTok. That‘s the spearhead of their innovation.
