If you have watched Everyday Astronaut's tours of Starbase with Elon[0], where he explains in significant detail pretty much everything that is going on with the various prototypes, you'll know what I mean.
He's not a guy with an MBA that has somehow lucked out by throwing gobs of cash at various Hard Engineering Problems (although there's that, too.) Of course the bulk of the work is done by "rank and file" engineers.
