The best thing about SpaceX, in my opinion, is how absolutely stunningly ordinary their basic business strategy is. Build stuff that's valuable using designs that are known to work, iterate on those designs as much as you can to improve them, charge people money for the stuff you build, and just continue doing that.<p>The Falcon 9 is a dead-simple 2 stage LOX/Kerosene rocket that effectively has a heritage back to the 1950s, as does the capsule based Dragon spacecraft. But SpaceX is continually trying to tighten their OODA loop and doing quite a good job of it.<p>It's a good model for a lot of startups. Build something, iterate on it, charge for it if for no other reason than to pay for continuing R&D, and just keep getting better until you change the industry.
