From what I’ve read, Musk has a complete understanding of physics and engineering.
OTOH, Steve Jobs went on and on about the influence of his calligraphy class in college.
Calligraphy?
Ha! That must explain Apple’s focus on innovative emoji engineering.
“Complete understanding” sounds like Musk’s self-promotion. What he understands is that by assembling a team of talented engineers, success is possible (but by no means guaranteed). Without that team, and a force driving it from the top, Tesla and Space-X would never had happened.
Understanding engineering and doing engineering are two different things.
