He is clearly a brilliant man based on his accomplishments. But he sure didn't seem that way on the show. I just don't get what he wanted to achieve with his appearance on that show.
I think he thought it would be fun to do. So that's what he did. I top of that, he just got a boat load of free publicity for himself and Tesla.
He got more publicity, no question. But not sure if it was the right kind. I for one, thought more of the man before this appearance. Not sure how acting like a naive nutcase will sell more cars.
What ever he has done so far hasn't done much to hurt sales. They are selling all the Model 3 and Model Y vehicles they can make. Heck, even some of the OEMs are trying to ride on his shirttails. Two sayings: "There's no such thing as bad publicity." "There's only one thing worse then being talked about, and that is not being talked about." Folks are buying a Tesla, for performance, technology, and their charging network.
Now looks like Tesla may have a China problem. https://www.barrons.com/articles/tesla-stock-down-china-ev-sales-51620739611 Having said that I am sure Cathie Woods will be buying up as much TSLA stock as she can today hoping her ARK will stay afloat.
