How do you know this? I find it very likely he has written some code here and there through the years. Whether that is Python, C++, Matlab or R, who knows. As chief scientist at SpaceX he at least needs to do some modelling on a regular basis that requires - at minimum - tweaks to some code.

What?! Do you know what the job of a CEO is? I answer your comment with your question. How do you know he tweaks some code? What proof do you have?

Board meeting -

"How's, like, the code that gets the spaceship in the air and back down again. Is it all working ok?"

"Yes Elon, should work fine. It's basically just typing."

"Great! Should work without any problems."

Sure, it's speculation, but remember that he is the Chief Scientist (think CTO) as well as CEO. Major technical decisions go through him.

In an Elon fan's eyes there's nothing he can't do !
