    I don't think that is very true in this day in age. Here in Cincinnati, the vast majority of houses now have fiber run to them. There are still some stragglers, but that's mainly b…

    The Android on chip AI is and has been leagues better than what is available on iOS. If anything, I think the upcoming iOS AI update will bring them to a similar level as android/g…

    Waymo's recent experiment with multimodal models and a purely camera based system (EMMA) validate some of the claims that using LIDAR data in training does help. Pretty neat! Still…

    Non-fuel uses make up roughly 10% of oil demand. Certainly significant, but unless plastics, fertilizer, etc have absolutely insane growth in the next 25 years, it won't keep deman…

    A Raptor engine has about 1/3 to 1/4 of the thrust of an F-1 engine. However, the Raptor is far more efficient and much more impressive technically. They are really a marvel of mod…
