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

    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),

    Dutch managed it, why wouldn’t the chinese, with a centrally planned economy that can directly integrate the different disciplines, be able to?

    packaging this into a system that meets the scale and reliability requirements to make it commercially viable hasn’t been reproduced to date.

    Communists in shambles - how could anyone fund science for the sake of progress instead of making money?

      • Dutch didn’t, not alone, far from that. Have a stab at the first link I posted: https://www.youtube.com/watch?v=RmgkV83OhHA

      • This will also show a long list of “honorable mentions” who failed, including the Japanese attempts (which, as you should know, aren’t exactly new to the game, way ahead of China and largely self-reliant in the matter, unlike China whose semiconductors industry has been centered around import of foreign tech)

      • I didn’t write that they “wouldn’t be able to”, I merely pointed the actual reasons why this is extremely hard (perhaps the hardest current Engineering feat, or why I find this whole thing fascinating), with speculations that this will take a while

      for the sake of progress instead of making money?

      no need to stretch it: if China wants to meet the ever growing domestic demand (either military or civil), China need fabs churning chips reliably. Simple as that.

        As opposed to the chinese, who are completely alone, all 1.whatever billion of them.

        which are[…]largely self-reliant in the matter

        You just fucking said it required cooperation you dumb cum juggler, now you’re saying they failed despite not cooperating?

        I didn’t write that they “wouldn’t be able to”

        I cannot sufficiently describe how much I hate your stupid reddit tier “um, akshumally I didn’t use those exact words therefore you’re completely misrepresenting what I said!” You won’t shut up about how hard and difficult and borderline impossible it is and you want me to believe you’re not trying to say they won’t be able to? You’re certainly not arguing that they will.

        if China wants to meet the ever growing domestic demand (either military or civil), China need fabs churning chips reliably.

        That’s not what commercially viable mean, buddy.

          no need to speculate, China is not at the same level today (or we wouldn’t even be having this discussion in the first place), no matter how populous. Would it help catch-up? Probably! You are the one bringing this up, not me, so…

          You just fucking said it required cooperation you dumb cum juggler, now you’re saying they failed despite not cooperating?

          Was this a difficult sentence to read? Should I break it down for you? Those two things can be true at the same time (which is essentially what I wrote):

          Today’s China has neither.

          You won’t shut up about how hard and difficult and borderline impossible it is and you want me to believe you’re not trying to say they won’t be able to? You’re certainly not arguing that they will.

          Well, I’m sorry that a well-sourced post with actual engineering and historical facts, meant for the legitimately curious and interested people here makes you so angry. What can I say other than “you probably didn’t check-out the links and are arguing in bad faith/for the sake of it” and “you are letting your emotions blur your comprehension, i.e. putting words in my mouth”.

          That’s not what commercially viable mean, buddy.

          Commercial viability is the likelihood that a product or service will be successful in the marketplace.

          Unless the CCP starts distributing indigenous chips asking nothing in exchange, which I find unlikely to say the least, those will be traded (against hard money, work, resources, …) on some form of market. I’m not really into arguing about semantics, so you do you.
