I finished reading the Elon Musk biography by Walter Isaacson, and, for all his faults, Musk really knows how to get shit done. I was constantly amazed by his ability to strip a process to its essentials before embarking on its construction. SpaceX single-handedly* brought down the cost of space flight by using off-the-shelf and custom-created-from-metal components, where they only had to pay for the raw cost rather than the markups by others (the "idiot tax" as mentioned in the biography).
Generally, I simply don't give a shit about what a founder says, I have a Toyota in addition to a Tesla, and I don't care what the CEO of Toyota says at all, so I always find it puzzling when people talk about their dislike of Musk in particular, as if that should matter when buying their products.
