I mean, even if you are right that Chinese manufacturing is superior, which is improbable, it still isn’t great for China. If it was cheaper and faster for them to develop domestic manufacturing, then it would have happened already. So while they build up, they will be non competitive with other manufacturers, even if they do have a strong product in a few years. Which again, is unlikely.

There are not. Chip manufacturing is extraordinarily delicate. You need incredibly precise machinery to operate in a vacuum with highly skilled workers. All three of these things react poorly to bombs.

If a Chinese capture of Taiwan is strongly opposed by just the Taiwanese, not even the Americans, then it will take just as long to reactivate TSMC as it would to build a new Chinese manufacturing base from scratch. If not longer, given risks of insurgents, UXO, and devastated infrastructure.

That’s fine. Developing a domestic chip manufacturing base is expensive and time consuming, so the US will have a major competitive advantage for the next few years. China may also be incapable of matching US and Taiwanese chip quality, which imposes additional costs. The goal isn’t “make sure China never builds a computer,” it’s just “make sure Chinese computers are more expensive so everyone buys American.”
