This is the kind of overly dramatic thinking that leads to stock market plunges.
China is an enormous country. It has over 4x the population of the USA. Unless you assume Chinese people are fundamentally different, it should be producing 4x the output in every field vs America. Yet the impact and legacy of communism is dire: China clearly isn't even close to 4x the productivity of the USA. How many companies on the leading edge of AI does the USA have? Meta, OpenAI, Anthropic, Google, NVIDIA, Cerebras, X.ai to pick just a handful of thousands.
Meanwhile Europe has produced one, Mistral (or two if you count DeepMind), and China has produced one. DeepSeek meanwhile, despite being impressive, has been doing the usual thing Chinese firms focus on of rapidly driving down the cost of tech already proven out by companies elsewhere. They have a long history of doing this and it's something they take cultural pride in, but at the same time, Chinese tech executives do worry about their relative lack of leading edge innovation. The head of DeepSeek has given interviews where he talks about that specifically and their desire to change attitudes and ideas about what Chinese firms can do, because there's a widespread cultural belief there that the Americans go from 0-1 and the Chinese can go from 1-10.
It's also worth remembering that prices in China are artificial. It's a somewhat planned economy still. Sectors of the economy with military relevance are heavily subsidized and they play games with their exchange rates, indeed perhaps in an attempt to forcibly deindustrialize the west. Just because something is made cheaper there doesn't necessarily mean they're doing it better. It can also be that they're just subsidized all the way to do that, and the average Chinese citizen is the loser (because they can't afford to buy things that would otherwise be affordable to them).
