2021 was a banner year for Elon Musk. CEO of the electric vehicle manufacturer Tesla, the aerospace manufacturer SpaceX, and a few smaller startups, Musk became the richest person on Earth after Tesla reached a market capitalization of $1 trillion and SpaceX a private valuation of $100 billion. Both companies made bet big on risky technologies. Now that they were leaders in booming industries, the task was to retain their lead. Musk had proposed a round of big new bets for each company: Tesla was to work with partners to rapidly expand battery production with a focus on lithium-iron phosphate batteries, and SpaceX was to launch thousands more of its Starlink satellites aboard Starship, the largest launch system ever devised. Meanwhile, Tesla faced litigation related to SEC complaints and safety concerns about its Autopilot driver-assistance system, and SpaceX's growing Starlink constellation similarly raised safety concerns. For Musk, the question was: should he consolidate gains and fix the operational, legal, and political problems before launching new initiatives, or should he proceed full speed ahead?
