BEIJING :China, the world's top processor of rare earths, banned the export of technology to extract and separate the critical materials on Thursday, the country's latest step to protect its dominance over several strategic metals.Rare earths are a group of 17 metals used to make magnets that turn power into
Hey, thanks for the constructive comment :)
True, but I don't think the end-goal is to "just" achieve technical sovereignty. Answering local demand requires production at a large scale
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.
