Hey, thanks for the constructive comment :)

[China] don’t give a shit about it being commercially viable, they give a shit about having the industrial capacity.

True, but I don't think the end-goal is to "just" achieve technical sovereignty. Answering local demand requires production at a large scale

The reason why EUV is more or less a cartel monopoly in the West is that it’s a cobbled together collection of scientific principles that work well enough that the first few companies that figured it out could make insane profits off of it

I really wouldn't put it that way, if you check my 3rd link out, you'd see that there were a few competing technologies on the table, and the topic was researched by national labs and a lot of public funding as well. Japan was also a leader and significant contributor but ultimately failed. It's not nearly as clearly cut as "bad imperialistic USA locks it down for rest of us": there is real international competition, and real international cooperation.

I can't predict where we will be at in 20 years. No matter what, we will be many generations beyond EUV. Other approaches that were deemed unfeasible before (=today) might turn practical in the future as fundamental research advances, and I suspect China will be strong in those areas, and, as you said, perhaps a leader.
