> Why are they doing any better than any other firm then?

Any other firm, you mean like the bloated and bureaucratic NASA/JPL/defense contractor madhouse? That's not much competition.

> Why has Tesla been successful? Why is xAI pretty similar in terms of approach? My idea has less variables than yours. It also doesn't fly with his tendency to fire people.

Your "idea" (statement) is that his companies are successful due to his micromanagement. In reality, they're successful in spite of it. Like all impactful engineering institutions, there are incredibly talented people working at the "bottom" levels of these companies that hold the whole thing together.

There's a good bit of irony here in your thought that he'd fire people that didn't agree with him or disobeyed him. From what I've heard, he lacks the technical rigor to even understand how what was implemented differs from his totally awesome and cool, off the cuff, reality adjacent ideas.

The myth of the supergenius CEO has real potential to influence investors, beyond that, the hard engineering is up to the engineers. Period. SpaceX wouldn't have gotten past o-ring selection with Elon at the engineering helm.
