There's a reason PRC has much more success poaching TSMC employees than US trying to fill up new fabs. Why TW has drafted laws to prevent TW semiconductor talent from working on mainland. Generally TWers prefer working in PRC, with comparable language / culture. Great compensation and quick flight home. Reality is most of TSMC employees will been prevented from being paperclipped to the US in event of war, their future will be firmly tied to PRC and as significant assets, they'll be treated with more carrots than sticks.
