Reading @zoeschiffer's "Extremely Hardcore" and one thing that is striking, though not surprising if you've paid attention to Musk at all, is his emphasis on the idea mattering.
It's this fantasy we've seen from the VC-crowd of "I tell the generative AI my Brilliant Idea™ and it executes it without any of these messy middle bits" (aka, people).
But ideas are cheap and they exist at so so many levels beyond just that one sentence summary.
I commented before that if you give a 8 year old a few billion dollars and you end up with a cloned woolly mammoth at the end, that doesn't indicate that the 8 year old is a visionary (no matter how many Mammoth Facts™ you get out of them).
It means that the problem was at most a few billion dollars away and you needed someone who either has a total disregard for the money (or who can afford to lose it and doesn't care) to actually execute on it.
