I think my main point was more that despite what you (not you personally, anyone reading) think of Elon, at least he has this track record of visionary companies and Sam does not.

Personally my take on Elon is something like this – he found a vacuum in the industry of smart engineers who want to work on something truly ambitious, the kind of people who feel most SV startups are bullshit. And as a sci-fi nerd he came in with money and pitched several sci-fi ambitious project ideas/visions that attracted these engineers etc. to make them happen. And I think he was rewarded for this. You could tally that as another vision that he had that was onto something.

well, you're definitely correct in that one of his superpowers is attracting some of the best talent to work for him (at least that was the case when he started Tesla and SpaceX). But you're completely overlooking his ridiculous work ethic (100+ hours per week for years on end), plus his own elite engineering chops (he was the chief engineer at SpaceX), and there are interviews of rocket engineers that worked for him stating that if you weren't on top of your game, Elon would call you out on it, even citing specific sections and page numbers of rocket science books on the fly mid-conversation. It's not just money he brought to the table.
