Elon is indeed difficult to predict, he always easily plays Doge for the sake of his product, or maybe also wants to make Doge last a long time with his controversy. 
Elon's career will not end just because of the Doge, he is already financially established even without the Doge Elon will still be brilliant.
That seemed true because he could easily turn around and go against what he had said earlier. Elon's career will not end just because of the Doge, he is already financially established even without the Doge Elon will still be brilliant.But we know Elon always creates controversy for the crypto market and maybe he wants to do it again this time.
We don't know what he meant by saying that but it could be true and he was serious about what he said.
I hope he doesn't do anything reckless in the future.
