It came from a long time ago. See the power of people like Elon was being rich enough they could throw money at shit with little risk and also be rich enough to get smart people to do all the good shit.
But he was the face of it all for a long time, people legit saw him as the person who brought in electric cars (yeah i know he wasnt) and thinking space x is the rival to NASA.
Many people idolized him as a genius.
Then he ruined it, and you know why? Because he opend his fucking mouth just like the podcast you're talking about and many people saw him for the idiot he was.
The problem? Elon himself believed the bullshit, he hinself thought he was a genius. And now hes trying to "run" things and its all falling to the ground.
Because he never realized the only reason he had anything good was because of the actual smart people employed there.
