State of the art chips are only partly starting to be produced with EUV. You can do 7 nm without. And even then you don't do all chips with 7, specifying all "high-end" as a race to the smallest node is completely insane, the design space permitted by "just" 14 has yet to be fully explored, and I'm not even talking about the other applications where you absolutely don't even want the smallest node. The strategy makes no sense at all IMO. This is a (very time limited) commercial war over gadgets, and this will clearly lead to China eventually developing and owning their whole stack.
