BEIJING : This Dec. 21 story has been corrected to clarify that the ban was on the export of technology to make rare earth magnets and that the ban on technology to extract and separate critical materials was already in place, in paragraphs 1 and 6. It also removes context and the comment on rare earth processi

    You obviously fall into the trap of believing that hard science cares about politics, and that money thrown at problems as part of national strategic planning magically solves them. But for anyone else legitimately interested in understanding the topic better and having a glimpse at its complexity, those are great resources:

    If the above is too advanced, this can serve as a good primer and answers “how the heck did we get there”: https://www.youtube.com/watch?v=Pt9NEnWmyMo

    Also, I never wrote that China will never get to EUV (or eventually something beyond that), just that it will take a very long time, because the complexity is spread across several very distinct scientific disciplines, integrating them is a challenge of its own (again, watch the videos), and packaging this into a system that meets the scale and reliability requirements to make it commercially viable hasn’t been reproduced to date.

      that’s cool and all but china has carrier-killer hypersonic missiles and ameriKKKa doesn’t

      EUV is complex, unlike nuclear weapons and energy, 5G, space stations, probes to the dark side of the moon and hypersonic missiles. Those things are simple.

        EUV is complex. And more so than the accomplishments you mentioned: nuclear weapons were cracked in the 1940’s, probe moon landings in the 50’s and space stations in the 70’s. All have since been reproduced by several nations in isolation. That is not the case of state of the art lithography. No single nation “owns” it because it truly is a multinational endeavor.

        (And actual hypersonic missiles haven’t made it to the battlefield, and 5G is about commoditization and standardization, by the ITU, an organ of the united nations, so I’m not sure exactly how that adds to your rhetoric)

        Way to put your ignorance on display.

          actual hypersonic missiles haven’t made it to the battlefield

          Really? Then how come Russia has had them in service since 2017 and China deployed theirs in 2019? This is just cope from western “military experts” online that can’t deal with the fact that Russia and China have better missiles than America.

            Again, not a military expert, but have you been living under a rock for several years and missed this whole Ukrainian “special military operation”?

            Russia’s hyped Kinzhal missiles, which promised to defeat air defence systems and be manoeverable at supersonic speeds are being shot down by 80’s era surface to air missiles. And I don’t think anyone has been in a position to assess China’s capabilities in the matter and I have no interest in discussing your beliefs.

            Edit: forgot to say this really has nothing to do with advanced lithography, anyways…

              There’s no proof of this ever happening, Ukraine hasn’t been able to provide evidence of shooting down even ONE kinzhal.

              Also, this has nothing to do with China’s hypersonic missiles.
