I too was pretty skeptical during the rise of Teslas stock price, but hey, clearly it was a good call by those who made it. After the pretty astronomical growth in price, I'm not sure I'd be plowing new money into it, but hey, no risk no reward!
Teslas biggest roadblock to scaling growth might be sourcing all the various battery metals they will need, especially in a tightening marketing with a lot more competition, both in the auto industry and other sectors. The world will really need to ramp up their resource extraction over the next few decades to meet this demand...which will be tough if environmental standards matter.

In the long run, Tesla investors might have been better served if Elon invested $50B into the resource sector, as opposed to Twitter.
