This might just be the thing that tips the scales in China deciding invasion of Taiwan is worth the risk. They're eying the Russian war warily though, if they can keep the United States distracted long enough and the EU at bay by continuing to bankroll Putin then they just might risk it. The window for that is closing though.
Counter point: It would be easier for China to develop the technology required than to invade Taiwan while preventing the fabs from exploding.
USA isn't paying close to $1 trillion to strategically re-home TSMC to Arizona for no reason.
China wouldn't be able to take Taiwan with the fabs not blown to pieces, and they know that.
