So many comments in this thread suggest Musk is an all knowing individual. "How could he miss this?" "I can't believe someone so wealthy can miss something so important!" And so on.

This is a really sad view, IMHO. Wealth may provide more opportunities to learn and expand, but that doesn't mean the wealthy know everything. He should have done his research, maybe he did and decided to go that route anyway, but wealth is only correlated to knowledge, not causative.

Edit to add: No defense for Musk here, I just hate seeing wealth equated to smarts.
