Pffft. They have done over 10 billion net in the past couple years. High ROE. They have a big, durable competitive advantage with their buying process v other companies (just go through the buying process across a number of car types). They have a big competitive advantage in staff capabilities, also in the ability to actually produce software.
Elon is no dummy. He targeted fat tired old industries to attack. It was brilliant. He now faces possibly the weakest competition in large business.
Suggesting it's worth less than $55 billion is silly.
