> Elon Musk is a smart salesman but that's about it. He has little deep knowledge in a lot of what he does.

No, I think it's the opposite — he's extremely knowledgeable about engineering and science [1], but quite hopeless at social things. If he was ignorant of technical stuff then SpaceX and Tesla would not have succeeded, and conversely if he was a good salesman he would have foreseen how badly his political actions would hurt Twitter and Tesla.

It's quite foolish to think someone is stupid or ignorant just because you don't agree with their politics.
