    Conversely: in humans, intelligence is inversely correlated with crime. It doesn't go to zero, however!

    Hopper had 60 TF FP64, Blackwell has 45 TF, and Rubin has 33 TF. It is pretty clear that Nvidia is sunsetting FP64 support, and they are selling a story that no serious computation…

    That's a surprisingly large overhead. I've not measured that large an impact on AMD, particularly for compute heavy. Did you profile at all? And have you observed if it's not compu…

    The manufacturing cost is emphatically not only 1% of the total development cost. Particularly for GPUs, the high bandwidth memory and manufacturing costs are a significant portion…

    > NVIDIA's control over the GPU compute ecosystem — particularly in AI, HPC The two largest supercomputers in the world are powered by AMD. I don't think it's accurate to say Nvidi…

    I do not find her critique of argument #2 compelling [1]. Monetization of AI is key to economic growth. She's focused on the democratic aspects of AI, which frankly aren't pertinen…

    The overall funding for starting up a laboratory is much smaller in Europe than the USA. It's that start up funding that will drive talent, more than anything else.

    While FP64 is indeed important for supercomputers, the largest supercomputers have a great deal in common with AI infrastructure. For example, high bandwidth, low latency interconn…

    As these are related to national defense and nuclear security, I've heard they are largely safe.

    Thanks! That's consistent with my impression.
