Solar rooftops hasn't gone anywhere. Boring company and Hyperloop didn't go anywhere.
Let's face it Neuralink isn't going anywhere too.
Tesla wasn't started by Musk and relies heavily on Panasonic battery developments and SpaceX and Starlink is good old fashioned ex-NASA and MIT talent.
What does Musk actually do? Annoy the SEC, go on Joe Rogan to smoke weed and have more girlfriends per hour than Gengis Khan?
