I'm generally critical of companies which have high valuations yet continuously lose money, but in the case of Musk's ventures, I think what he's doing is so genuinely innovative that I would be more inclined to put the blame on the system than on Musk himself.

Elon uses long-term thinking but unfortunately our economic system tends to favour short-term returns. In my mind there is a huge difference between Tesla losing money versus Twitter losing money - But to an economist, it's the same kind of beast.
