  • There’s nothing reasonable about these assumptions.

    There’s no way the VisionPro gets even close to 100W. Why? Because heat dissipation. The vast majority of power drawn by semiconductors is dissipated as heat and, in a device that’s strapped to someone’s face, there’s simply no way to dissipate hundreds of watts.

    Also, knowing the battery pack size and battery life, it’s easy to guesstimate the power consumption.

    “The Apple Vision Pro provides approximately 2 hours of battery life. Based on its size, the internal battery capacity is estimated to be within 20,000mAh (74Wh), resulting in an overall power consumption of around 30W.”

    Even if we assume the double of that 30W, it’s well within USB-C standards.




  • And if Japan hadn’t surrendered, it would have been used up to a dozen times.

    The third bomb, and the others that may have followed, were a definitive part of the American strategy to end World War II. Although hopeful that nuclear weapons might end the war, American officials—from President Truman to his commanding officers—did not expect the war to end right away. Signs indicated that more atomic weapons were necessary, and U.S. leaders were rapidly moving to order more atomic strikes. Had the war continued, more atomic bombs would very likely have been used.
