As we chronicle every week on Elon, Inc., Elon Musk contains multitudes. He leads six companies, runs his own social-media platform and is now explicitly working to re-elect Donald Trump as president. This week, we talk about two very different kinds of Musk stories. One is about his behavior on X, and the rare tweet he took down. The other is about how his space company, SpaceX, is having a great run of late, with a successful space walk and a new deal with United Airlines.
