Used to be that the US would just import scientists and engineers then develop stuff themselves. It'll be interesting in a few years to learn if this Arizona plant was just one head of the capitalist hydra and its success or failure didn't really matter all that much. I suspect that the US doesn't need to import technology in that manner to get good results; it never has in the past and I don't think that much has changed.
All the excitement over high end chips seems overblown. We appear to be talking about a couple of years R&D. Tactically interesting, it'll decide a lot of things in practice about who specialises in what. Strategically not that big an issue. The trade war manoeuvring is doomed to look silly; the US can't stop China and China couldn't stop the US anyone thought there was a real problem to solve.
