Honestly to me all these comments are wrong and focusing too much on the 2nm aspect and not the possible r&d outcomes. EUV come to fruition because of r&d research between the US and other countries/companies. TSMC might be the largest foundry but a majority if not all of their tooling is from the west and japan; from ASML, AMAT, Lam Research and others. Best believe some acquisitions will happen especially on from the US side and new tech will be coming out probably some sort of EUV replacement.
