It feels to me that Elon Musk very much is Tesla. His own personal engineering and design decisions can be seen in the final product. That's probably rare for most CEOs of large companies. For good or bad, his personality and the way he operates is the culture of Tesla. In the end I'm sure that Tesla can survive, but something won't be the same.
Tesla's future aside, I'm actually worried what this may do to Elon's mental health. In the recent Joe Rogan interview, there was a moment when Joe asked Elon what the world would be like if there were more people like him. Elon's response was:
I don't think you'd necessarily want to be me. I don't think people would like it that much. It's very hard to turn it off. It might sound great to turn it on, but what if you can't turn it off?
The look of Elon's face was one of a very tired man. Not sleepy, but almost tired of all the crap that is slung his way.
The world still needs Elon, so I hope this doesn't stop him.
