I don't know about that. I'm a physicist myself and found his 2016 IAC presentation embarrasing. I wasn't expecting a crewed spacecraft inside the Jupiter radiation belts, nor a 70s artist impression of the surface of Europa. I don't know yet how he's going to shield people inside those empty shells, nor where's the money for the mind-boggling infraestructure you need before all that starts making sense.

But he has a torch and pitchfork fanbase, so we can't really have a grown-up conversation about that.

I've never read any BS authored by Einstein or Hawking, so I can't understand your comparison.
