Elon built a new car company that is, probably, at least as long-term viable as BMW. Though the valuation of 3X that of Toyota is outlandish. That valuation is based in large measure on the prospects of robotaxis. Similarly, the SpaceX Falcon 9 and Crew Dragon are huge successes. But the valuation of SpaceX is largely based on Starlink becoming a global telecom giant, and that, in turn, is based on 2nd gen satellites which can only be flown on Starship. What Musk's brief time at Twitter has shown everyone is that he can fail on a scale of tens of billions in less than a month. Betting on LEO telecom and robotaxis, nevermind tunnels, brain implants, and Mars colonies is high risk, and the last person you will hear tell of those risks is Elon.
