    Remember the part of the article where he talks about a shocking number of people didnt have the version of AVX he wanted. This is a big issue because SIMD is writing ASM for the m…

    Imagine you have pictures of someones baptism and the kid was nude. Is it CSAM? I think the program would have to say use but morally I'd say no. The issue with client scanning is …

    Well I mean not from the waste heat but they have expectations of GigaWatts of new sustained power because they always want to run. The US has on order of 1-2 Tera watts of power c…

    Yeah I tend to agree with this point. PE is a boggie man for not building enough housing where it matters. In fact if we could build more houses PE could buy it at above market pri…

    I think there is a huge problem that the American Zeitgeist views houses as the only way to build generational wealth. It turns housing into an investiment and investiments need to…

    I think all your points are correct except the AI making the economy less capital intensive. Its a new type of input that is suppose to make you vastly more performant not having i…

    I don't won't to rant politically but I think you are confusing Donald Trump's America Alone with all previous Republicans and Democrats. The idea of us abandoning all alliances an…

    Thank you for the clarification! When you say you put a lot of time in do you mean as a developer or just game time? I find it facinating how that worked. I personally enjoyed the …

    I think the idea that sites have no liability for customly built content designed to capture your attention is kind of wild. It would be one thing if it was a basic or public thumb…
