This gets it backwards, though.
If you watch how Musk engages with the public, his fans in particular, over they years it's often the fans making a bunch of sci-fi bullshit promises that he accepts.
SO MANY TIMES I watched idiot fans asking Musk if he was going to do whatever, and he'd even push back to say no that seems unlikely, and they keep pressing until he just says, "Yeah, whatever," and lets them have it.
This is a pattern that has played out so often with so many public figures, and I think with increasing frequency in the social media age.
I wish we were all more aware of it.
If nothing else, it basically made Trump.
