How SpaceX streamlined the Raptor engine

    According to Isaacson's biography of Musk, Musk relentlessly challenges the existence of every part in Tesla and SpaceX machines. He's willing to go too far, having to sometimes put a part back in.

    Everything in the manufacturing process is also challenged to justify its existence.

    This is how he managed to reduce the costs by 90%.

      > According to Isaacson's biography

      Isaacson’s “biographies” are glorified puff pieces. Musk is as unrecognizable in his as Jobs was in his.

      Both Tesla and SpaceX had teams keeping Musk busy on bs just so that the engineering teams could do their work.

      The second he took control, we got the cybertruck and the starship, the worse products both companies ever built (or attempted, in the case of the starship).

      > Musk relentlessly challenges the existence of every part

      This sounds insightful until you find yourself debating with the CEO for the eleventh time about how his high-school understanding of the physics involved breaks down in a particular case.

      Musk is very lucky to be moving such quantities of money that his companies are big enough to protect themselves from him, if you ever wonder how Musk would fare on a tight budget, look no further than the Oceangate.

        Do you remember when he bought Twitter and fired everyone, and the mass media and employee outcry was that a) the service would stop working and b) he would bankrupt the company, yet a few years later it’s massively more successful than Twitter ever was as a public business?

        Regardless your thoughts on Elon, his drug habits, and his political brashness, I don’t think you can say he’s in any way close to the Oceangate guy. There is something legitimately special about him and his collective.

          Twitter is definitely not more successful now than before. So many people left and are gone forever.

          I would read a deep dive though into the history of Twitter (with the financials) to understand better and I do get that for a single product company there really is a point at which you give up on finding the next big thing and just optimize on your main thing and you really just need a few dozen awesome people and a rotation of new hires to keep things rolling but not thousands of engineers.

            Maybe I’m overstating “massively more successful” but to my understanding “X” has roughly twice the active use count that Twitter did, although that includes Grok.

            That said, do you remember these kinds of articles?

            Elon was firing people left and right and literally physically destroying Twitter’s data centers. I remember hundreds of these hysterical articles and tweets that very clearly did not come to pass. He obviously did something more clever than the authors of these articles expected… is all I’m claiming.

              I haven&#x27;t posted anything on this HN submission yet, but all I&#x27;m claiming is that Twitter was so successful under Elon&#x27;s management that he thought it was better to roll it into SpaceX than to keep it independent. Kind of like solar city was merged into Tesla to bail it out and then it winded down after the acquisition while nobody is looking.

              Just claiming, you know.

                Yes, and Tesla and SpaceX are both ridiculously overvalued by any fair measure.

                But we can separate the financial inanity of his empire from the question, which is whether Elon is a capable engineering mind or simply an ‘Isaacson puff piece recipient’.

                  Isaacson could write the puffiest puff piece about me and I&#x27;d still never become a trillionaire.
