That would be fine if the US and China were great friends and allies - like if it was the UK instead of China that was the semiconductor powerhouse. But things look stormy on the horizon. Even discounting a military conflict with China (not likely anytime soon, I think) an economic conflict seems very possible. As China begins to manufacture a larger share of semiconductors they could easily decide to favor their own internal industries that are customers of said semiconductors and not allow state-of-the-art chips to be sold outside (or to certain countries). We (the US) have done similar things in the past.
