You know what is really going to be fukked up? The next generation of computer ships (only a few nanometers) have only been mastered by TSMC in Taiwan and Samsung in Korea. Intel announced they are outsourcing their next generation processing to TSMC as are a bunch of others. About 20 years ago there were about 20 semiconductor foundries and there are now only a few, of which TSMC is the most powerful. They are building a massive new plant in southern Taiwan.
If shyt goes south in Taiwan, the global semiconductor industry is fukked with no recovery plan. There are no next generation chip factories in the US and investment takes about $50-100B to make one of the next gen foundries. People in the chip industry are actual getting scared how concentrated it is.
I heard a rumor once that TSMC keeps all its advanced fabs in Taiwan as part of a ROC government policy of ensuring the US/Japan will defend Taiwan out of economic necessity since the chipmakers need Taiwan at this point. If Taiwan gets attacked I could see them loading these factories into C-5s to make sure PRC doesn't get hold of them.
