Musk is a competent manager, amazing bser, but he is not a genius.
edit: Competent manager is not a slight. There are very few competent managers these days.
I doubt Musk originated these idea but he was the one who ultimately made the decision on them. There were a lot of other people who had the same choice and either didn't come down that way or took a lot longer to come to the same place.
Like I said, genius? I personally wouldn't use that word. He's not an idiot though. He might be the minimum viable product for technical knowledge combined with a large amount of money but that's still pretty remarkable.
EDS is so weird
