The American Physical Society interviewed Elon Musk.

But even if someone has no intention of ultimately being a physicist, I still believe that the training of physics is excellent. So as they’re going through their academic career I would recommend studying physics as a good base and then a broad range of engineering courses and then some degree of specialization in an engineering field where it fulfills someone’s interest, and then arts and sciences courses, particularly history. And a few business courses are helpful so you at least know the terminology. You can probably do it with one accounting course, [although] I hate accounting. It’s worth it to have some business courses but you don’t need too many. And I wouldn’t recommend an MBA. I’d say no MBA needed. An MBA is a bad idea.

It teaches people all sorts of wrong things. They don’t teach people to think in MBA schools. And the top MBA schools are the worst. Because they actually teach people that you must be special, and it causes people to close down their feedback loop and not rigorously examine when they are wrong.

I hire people in spite of an MBA, not because of one. If you look at the senior managers of my companies, you’ll see very few MBAs there.
