Another factor here is that to make the most advanced chips, you need something called eleven 9 silicon. That’s silicon that’s 99.999999999% pure.
We can only artificially manufacture up to nine 9 silicon.
Eleven 9 has to be mined, and there’s only one spot in the world were it exists. A little town in North Carolina.
That’s why the US gets to say who can even attempt to manufacture advanced chips.

As I said, we can make nine 9 silicon. But not eleven 9. China makes billions of nine 9 silicon chips per year. But they can’t make eleven 9. Everyone is trying to create lab made eleven 9, it might not be possible. The natural stuff formed over hundreds of millions of years with basically no exposure to water. Which means no contaminates.
So yeah, we’ve not succeeded in recreating that.
