This.
I've tried to write a quick post just after the Falcon Heavy launch:
How to grow a generation of space explorers — Steemit
I think that Elon has an uncanny instinct in appealing to young people.
He thinks from first principles, so he always thinks about the next generation of customers, engineers, computer scientists, space explorers. His gimmicks (sendind a f***ng car through space, with Spaceman listening to Space Oddity, and all the other nerdy things) are understandable/wowable from 6 year-olds to millenials. He'll be probably responsible for a lot of guys and girls choosing scientific faculties in college. And, of course, he's cultivating a lot of customers of the next 5-10 years.
This is why I'm constantly hoping he'll really make a 35k car, or even less: young people have more time but less money. Tesla Network will help, of course.
