If enough usage picks up in this fab, the supply chain will build around it. The hard part (and TSMC has said this is an issue internally as well) is replicating the business in the US. The work ethic, job expectations, cultural taboos, etc are all different. If it turns out that TSMC can only do what they do where they do it because of a bunch of external factors, then no one is going to be putting their billion dollar business here. Especially if they can save a few million by doing it in Taiwan.
