Edit: Wow, so much hate for a one-line comment. I have five replies and three downvotes as of now.
I stand by my comment. I think Tesla is building long-term value (brand recognition, a reputation for innovation in an stodgy industry, technical know-how in multiple industries) that will allow them to be profitable. I know well how Amazon got here, but I don't care about the technicalities. It is the behemoth that it is because of the compounded value added over 14+ years. I see Tesla equally driven and able to take advantage of the things it puts in place now.
