  • I mean comparatively to HDDs.

    Of course there are also challenges to making a high capacity SSD, but i don’t think they are using fundamentally new methods to achieve higher capacities. Yes they need to design better controllers and heat management becomes a larger factor, but the nand chips to my knowledge are still the same you’d see in smaller capacities. And the form factor has the space to accomodate them.

    If HDDs could just continue to stack more of the same platters into a drive to increase capacity they’d have a much easier time to scale.



  • Your claim that they would advertise it is speculation. What would be the purpose of that?

    To advertise that they can? In return what would be the purpose to hide it?

    They do seem to make their advancements at least somewhat public, e.g. with their recent progress with a EUV light source.

    I am probably on the pessimistic side and you maybe on the optimistic, so the reality will likely end up being somewhere in between (but only time will tell).

    China will do this because they have massive talent mass and ressources, and because they have to.

    Well it also was developed in the west by a large amount of talent and resources and still took a lot of time. But you are absolutely right that their hand is being forced.

    Restricting exports like this imo was a huge mistake, imo especially in regard to duv. In the end it might have achieved some damage in the short/medium term, but that wasn’t anything the us could capitalize on and it also directly hurt ASMLs profits (meaning less resources to advance). And regardless how the timeline ends up looking on the end (be it closer to your or my prediction), physics are the same everywhere so that can’t be restricted and they will eventually be able to figure it out.


  • GAA is the next evolution of transistor architecture from FinFET, but as far as I know has no direct link to smaller process nodes. In that (to my understanding) it doesn’t require small nodes and could be used just as easily in larger ones. It’s just that it is more difficult so until now there were other easier ways to make progress. However with new nodes getting more expensive and giving less scaling gaa and other things like backside power delivery are being pursued.

    We will have to see if the process is actually good, but I have little doubt that China will become competitive in EUV within 5 years. But if they have it already next year, that will be very fast.

    So not only do you expect China to have a working domestically produced EUV machine within 5 years, but a competitive one? Or possibly even next year?

    Next year is just pure fantasy that I don’t think even the most optimistic would assume. If they were anywhere close to that we would already know. They’d have shown a working prototype by now.

    Euv is crazy difficult and you not only the result of a single company ASML, but many highly specialized companies that are leaders in their respective fields and all over the world like e.g. Zeiss for for the lenses. So for China to replicate it domestically they’d need to copy the whole supply chain. Which is orders of magnitude more difficult than what they’ve done in other industries like electric vehicles or solar panels.

    Imo if they have a working prototype of a complete EUV machine within this decade it would already be impressive. But that would still be far off from mass production or wherever the industry is by then (Intel is currently trialing high na EUV). Also for reference Wikipedia says ASML had their first prototype in 2006 and we know how long it took to being that to mass production. China as a second mover might have an edge that speed things up, but just knowing how it works in theory isn’t enough and there are o shortcuts.

    But maybe they also pursue another technique such as nano imprint (like canon) to achieve smaller nodes. Maybe that would be easier to replicate without existing global supply chains.


  • Well there are claims that Huawei is aiming for 3nm with GAA with tape out next year See Here.

    I think we shouldn’t forget that the nm numbers really are just that: Numbers. They don’t correspond to any specific measurements and can be chosen more or less arbitrarily. So 6nm for example might just be a slightly refined 7nm node.

    Another thing is power efficiency and yields. If they get 4060 performance at terrible yields and with massive power draw then it is very different to getting there at similar parameters as Nvidia.

    If China does end up cracking EUV by themselves it would indeed be massive. It’s arguably one of the most complex things mankind has ever done. But there are so many factors to get right that tbh I don’t see it happening any time soon.




  • Considering her future job as queen will involve a lot of diplomatic and ceremonial functions it does kind of make sense to me that you’d want her to gain some international experience.

    Also on a personal level i’d imagine it is much easier to have some resemblance of a private life in a foreign country, especially at a prestigious institution where plenty of others share notable backgrounds, compared to going to a local university where everyone knows who you are. In a small country like Belgium you probably don’t even have much choices as to which university even offers a good program in your chosen field.

    Edit:

    Elisabeth initially studied at St John Berchmans College in Marollen, Brussels from September 2004 until August 2018. This marked a significant change in Belgian royal tradition, being the first time that a future Belgian monarch’s education has begun in Dutch

    In May 2020, the Belgian Royal Court announced that Elisabeth would undertake military training. On 31 August 2020, Elisabeth entered the Royal Military Academy in Brussels, studying social and military sciences

    Really seems like the worst candidate to make this accuse against



  • Another aspect of why it often is better is that it allows them to avoid paying taxes on sales and already accumulated profits, which is desirable because of the compound interest effect.

    I think if using something as collateral for a loan would create a taxable event and eliminate this advantage, then they would care a lot less about the arbitrage play between interest rates and average long term stock returns.

    From what little I’ve read more like Francis, which isn’t surprising considering he appointed the majority of those who just voted.

    Apparently he’s a bit more moderate. Similar focus on the poor and immigrants, which apparently Leo 13 was as well (name choice is also a statement, so reading up on whoever has the name before might be worthwhile). But slightly more conservative in regard to lgbtq and women.


  • There’s currently a Kickstarter going on for a watch that aims to be modular and repairable. It’s called UNA Watch.

    Look interesting, but imo with these things it’s a bit of a chicken and egg problem, where the upgradeability/repairability only has value, if it is actually provided in the future (and economically viable). Something that can only be proven in time, but requires people to trust it before.

    I’m not in the market for a new watch right now, since I just repaired the screen on my Garmin, but am keeping an eye on it, since sadly Garmin seems to have entered the early stages of enshittification.


  • Agreed. The prequels have flawed execution, but imo a good base. It’s the reverse with the sequels that are mostly style over substance, chasing some pretty shots regardless whether it makes for a good movie. And I take the former over the latter any day. Especially if we remember that Lucas asked other directors to make them.

    I’d say the most recent major influences were the IPO and the emergence of LLMs.

    Reddit becoming a publicly traded company and the preparation to do so certainly initiated a major shift in its priorities.

    Ai and large language models make it easier than ever to create shiny, but low quality content.

    And the rest is just reddit becoming more mainstream leading to an overall shift towards banal rather than niche topics.
