I'm not digressing at all. Your argument is that EUV tech is somehow exceptionally complex, therefore China cannot create it's own version in a reasonable time frame. The direct response to that claim is to point to examples of complex technologies that China has mastered and advanced.
China leads the world in new patents and has mastered several technologies which even America has not. Given that the current leading purveyors of EUV are the frickin Dutch, not the Americans, there's no basis to claim that EUV is exceptionally complex such that the world's leading scientific and econmic power cannot reproduce it.
Same response as https://programming.dev/comment/5908167 ; I never wrote that China cannot create it's own version, but that it will likely take some time. Reasons for this complexity are also mentioned in that post.
I get where your impression comes from, but I highly recommend watching the video about EUV's history (https://www.youtube.com/watch?v=RmgkV83OhHA) to better weight the contribution of every (international) party.
