There are trillions of dollars at stake in the launch industry that SpaceX is trying to seriously disrupt.
There are trillions of dollars at stake in the ride-share/taxi industry that Tesla/Elon is trying seriously to disrupt.
There are a lot of people who are working very hard to paint a very negative picture of Elon/Tesla/SpaceX right now.
It's amazing that stories like this make headlines while the news that the Tesla Model 3 is outselling every other electric vehicle combined doesn't make a blip.
Follow the money.
And yet if you do this at the actual companies (SpaceX, Tesla) or industries (rideshare) you mention, most traditional economists will tell you they have questionable futures based on their balance sheets (all of them have been consistently losing extremely large amounts of money for years) and some believe they will actually go to zero. So by following the money, it's not hard to see why some would think these companies are overvalued.
United Launch Alliance, SpaceX's main (only?) competitor pulls in a few billion in revenue a year. Profits are well under $100 million, so we're talking Trillions over a couple thousand years. Arguably, if we're disrupted into a spacefaring species, this could change, but there's physical problems with that.
You might be correct about rideshare/taxi industries over a 100 year timespan or something, but not before Elon dies.
So that leaves car industries. Which are the closest, but EVs aren't going to take over any time soon, and other carmakers are better at logistics than Tesla, and that's the important part.
Ask Norway.
Please elaborate.
