  • 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





  • 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.

    Not sure if it is still relevant and i’ve also not kept up with all hardware releases as i’d like to. But some thoughts:

    • You could look into the Thermalright Phantom Spirit 120 SE (or Peerless Assassin, think those are both fairly close). Those are just ridicolously cheap at ~$60 and if you look at reviews give much more expensive coolers a run for their money.

    • Not sure what the current verdict is on whether PCIe5 drives give a significant upgrade, but if not you could look at a drive like the Silicon Power US75. When i last looked at SSDs Newmaxx spredsheets and flowcharts were a useful resource and based on those it ticks the boxes for a solid drive.

    • As someone else also already suggested some faster RAM might also be a cheap and worthwhile upgrade

    • Motherboards are just way to complicated for me to make a deepdive to get up to date again. So i’ll just say that imo Hardware unboxed always has some of the best video roundups. But i think there might potentially be room to get something cheaper and in return invest the saved money somewhere else. Just decide what features you actually need and imo don’t get too hung up on potential future upgrades. Will your dad actually make those upgrades? And would spending $100-150 for a slightly better upgrade path now really be worth it compared to spending them somewhere else. Either on the build itself or peripherals like a nicer monitor etc.

    • I assume the case is already purchased based on the list? Otherwise this might be something to let him choose somewhat based on looks.

    Just as a hypotherical example with all changes it would look like this atm ~$2900 vs $3300. Note that i just put in a cheaper motherboard, but didn’t really read up much on it, so that would require some more investigation. This would either make it cheaper or leave room in the budget for other things like an even better GPU/CPU or on peripherals. Really depends on what he plans to do with it.


  • Sadly I think Airbus is already busy as is. As far as I understand it, they were already supply constrainted before this and have their order books filled for years. Otherwise Boeing’s most recent quality and safety issues would have had a larger effect.

    I don’t know if they could increase capacities even if they wanted to, or if a volatile situation like this would allow for the investments that would be necessary to do so.

    Imo this just accelerates China’s own ambitions to build up their own rival with Comac. This development makes the transition less gradual and they’ll have to eat some losses, but that’s something their system is capable of.

    On the other hand it’s actually worse for the US, because they’ll miss out on those sales and might not be able to sell them somewhere else. With Boeing already struggling and this being a key industry, this will mean that it might require more subsidies in the future to keep them going or succeed in the turnaround.


  • Does this actually matter that much? I have a pixel 6a that has the visor style camera bump and with a case on it just disappears.

    And even if I’d use the phone without case Google’s bar shaped design still allows the phone to lay stable on a surface without wobble, just at a slight angle instead of flat. Which I guess would be an issue with other designs.


  • As i understand it most of the money they are investing goes into new datacenters. So when a model gets outdone by a new one they still have those, unlike e.g. OpenAI that use other companies resources (i think microsoft and oracle mostly?). In a way companies that use those external clouds to train their own models are financing the investments needed for the big players.

    AWS, GCP and Azure are all growing 30%+ yoy, are profitable and if anything supply constraint in that they can’t build more capacity fast enough to meet demand. So it seems to me that to some degree they are already recouping some of those investments. I don’t see a drop in demand for compute, and even if using/training ai would become less resource intensive, Jevons paradox would just lead to more demand.

    Of course they also burn a lot of money as anytime a new model gets trained and beats the older ones, it kind of renders the resources spend on the previous one worthless. But to me that seems like the cost of doing business.

    The current investments they can afford. What would actually lead to shedding huge amounts of marketcap is, if they’d let a rival establish themselves. Similar to how the movie studios didn’t get into streaming early (mostly to not hurt their cable business) and gave Netflix enough time to establish themselves.


    To comment on something you mentioned in another reply below:

    I just don’t see a world where most people are coughing up more than $10 a month for AI.

    I think the big money will be in the business world, where salaries for actual people are high enough that saving a person even a few hours/week or replacing a single employee saves so much money that even expensive subscriptions would easily be worth it.

    On the consumer side as you say running smaller models locally will likely be the norm. But that means it would be free for both the likes of Deepseek and Google. And then it’ll just come down to who has access to personal information and is better embedded, which would be likely be whoever also controls other aspects of a users life, such as Goole with Android, gmail etc. Money here will be made just as it is done with other free services.
