The only thing relevant for the US re risking starting this niche is brain drain and talent. The market is always growing, they already have vertical demand (power tools and simple car chips), and new more-local competition can never be dismissed.
It always comes down to the people at the end of the day. Your 2nd paragraph quote where they are declaring this a successful example of public/private just because the factory was built is a bit concerning to me. They’ve mearly just begun.
