Earlier quoted context omitted.
I have two separate and (mostly) unrelated feelings. Musk has done something remarkable as you say. At the same time, the market cap is nuts and a portent of doom. Bigger than all car companies combined, by market cap? A market crash could take down Tesla and set back electric car adoption by 20 years.
Lets start with two assumptions. In 10 years, majority of cars sold will be electric. Majority of cars sold will have self driving capability. Tesla is a leader in both. Much of the traditional knowledge companies have about ICE engines do not help them build a better electric car. That knowledge is worthless for the future. Stock price represents future value.
True, but look around at the electric platforms being developed by traditional car companies. Mercedes has one, BMW has one, VW has one, Nissan has one, etc.
Most of them will be transitioning. The stock price represents future value where that value is Tesla absolutely crushing everyone else, which we can now say with ~80% confidence won't happen. Irrational exuberance.
