The question is when? Does that come in time to deflate the US tech stock bubble? Or will the bubble start to level out and reality catch up, or will the market crash for another reason beforehand?
This is like this funny idea people had in the early 2000s that China would continue to manufacture most US technology but they could never design their own competitive tech. Why would anyone think that?
Wrt invading Taiwan, I don't think there is any way China can get TSMC intact. If they do invade Taiwan (please God no), it would be a horrible bloodbath. Deaths in the hundreds of thousands and probably relentless bombing. Taiwan would likely destroy its own fabs to avoid them being taken. It would be sad and horrible.
They’ll just catch the next wave of tech or eventually break into EUV.
There are so many trade and manufacturing links between China and Taiwan that an outright war would be economically disastrous for both countries.
That'd be the belief in good old American exceptionalism. Up until recently, a common meme on HN was "freedom" is fundamental to innovation, and naturally the country with the most Freedom(TM) wins. This even persisted after it was clear that DJI was kicking all kinds of ass, outcompeting multiple western drone companies.
Everyone is still dependent on a single American manufacturer for this tech after decades of development. This strongly suggests that it is considerably more difficult than just "funding a second source".
