Have you heard of Operation Paperclip? The moment China steps in Taiwan, all those vital TSMC engineers will be flown to the US along with the critical IP and given a blank cheque to replicate Taiwan operation on US soil ASAP. TSMC is preemptively building the infrastructure there in preparation for such an event, so it can outlive whatever happens to Taiwan. TSMC has little inventive to tie itself to Taiwan and its people who are not its employees. Every big company thinks and acts like this. Taiwan can't force TSMC to stay there if it doesn't want to.
Reminder that TSMC WANTs to stay in TW... they did not want to expand in US at all. Arizona fab annoucement after months rumormill was big surprise at the time since TSMC did massive TW capex expansion and had no $$$ for US fabs, and it was combination of CHIPS carrots ($$$) and US sticks that got Arizona greenlit. Morris Chang publically said CHIPS would fail to get US semi leadership, that US policy is "doomed" / "futile", that is not the words of someone who wanted to erode TW's silicon shield. IMO TSMC Arizona's current (likely ongoing) dependence on imported TW talent makes it pretty clear TW is keeping tight leash.
>Taiwan can't force TSMC
IIRC TW foreign minister said a few years ago it was pure American wishcasting to expect TSMC employees to be evacuated before TW women and children. Around the same time TW politicians rebuffed the idea that TW would destroy their own fabs. That's TW's leverage, they control who gets on and off the planes and boats. Reality is if PRC makes a move, they'll lock down the airfield and shores, that's PRC's leverage - to control if planes and boats get to leave in the first place. Ultimately, TW politicians knows locking semi talent on the island is leverage, especially if they lose, because most of them won't have a ticket off the island.
Not to mention paperclip is the victors getting the spoils, and US is far from assured any victory or there would be any TSMC employees left to paperclip if motivated PRC wants to deny. Or that TSMC is like 70k people excluding their families. 300k if you include other direct TW semi employment. More if you include indirect (supply chain), and ultimately there's considerable sole source semi suppliers on TW that TSMC US won't be functional just like how ASML can shut down hardware by stopping inputs for maintenance. It's not just packaging and domestic talent that's another bottleneck, TSMC Arizona stops with TW inputs as much as it doesn't without ASML ones. And so far there's no real public plan to reshore that supply chain in US.
I don't see how this is relevant or invalidates my point. You think the US will wait for the end of the war to do that or what?
Also, German scientists who could leave the country were fleeing to the US before the Nazi regime started WW2 and also during the war, before it was a formal operation to gather them as prisoners of war when Germany lost.
How is the US going to extract a whole bunch of Taiwanese citizens from an island which will be under a Chinese naval encirclement?
The point is that Operation Paperclip happened in the aftermath of a total strategic defeat of the German army, where the Allies were the victorious power.
Taiwanese scientists and engineers are currently living happily in Taiwan, which is not a fascist regime cracking down on civil liberties. So they're not going to flee before the war, and once the war starts "extract significant numbers of educated personnel" is literally identical in military complexity to "fight and defeat the Chinese naval blockade".
