We seem to think that with every sport at every point in time, and eventually we have to be right, but there is no way of knowing until it happens. New training, diet, technique, and equipment could always be developed that radically advances a sport, not to ignore the occasional genetically gifted athlete who is just literally built different.

    I don’t think the Apple one at least is any kind of AI/LLM, just a message that plays asking you to state who you are and your reason for calling, then it shows a transcript on the phone ringing alert for you to decide if you want to answer or not.

    Even if you had wires on both ends of the pole, nothing would go into the person because the path of least resistance would be the pole. You would have to energize the pole and directly connect the person to the other wire in order to complete the circuit. Then the resistance of the human body becomes an issue, and using this paper as a reference, the worst case scenario of internal body resistance is ~300 ohm, and the threshold for immediate cardiac symptoms is ~100 mA.

    Then, 12V / 300 ohm = 40 mA. So closer than I’d like, but probably not fatal even in the absolute worst case scenario where there is no electrical resistance provided by the skin and a direct electrical path through the heart.

    The image is a poorly executed FDM 3D print stylized version of the image Wikipedia image I posted, and metal 3D printing costs much more than the few cents quoted in the tweet.

    Even if you were to 3D print the nut in metal, it wouldn’t be as strong as the machined original due to porosity and such, and being as that is the nut that holds the helicopter rotors to the helicopter, making it weaker would be very ill advised.

    Funny joke, but before anyone assumes this is real and criticizes the print quality:

    Both of these photos are edited from the picture on the Wikipedia page for the rotor retaining nut. The one on the right doesn’t even look like a real 3D printed part: the lines on the top surfaces aren’t parallel, in addition to it being incredibly messy overall.
