The US has created a network of semiconductor facilities around the world in the US, Israel, Taiwan, the Netherlands, etc. They all operate under the US licensure. And Trump is increasing the number of FABs in the US. They aren't going to fall behind in one month or so. But even if so, China might be able to produce the best products, but what will happen when it cannot sell them to large markets in the US or Europe?
Honestly, I think Gemini and Anthropic are leading AI at the moment. I have never seen a model perform as well as Claude on large datasets.
Unfortunately, these countries follow the US voluntarily as well. Europe knows it is irrelevant without the US and they're not going to give up on the US any time soon as they believe the US to be the lesser two evils. It's a combination of racism and Judeo-Christian principles.
