If by intelligence, we define it as the standard/stereo type of cognitive capacity or expertise, dude is above average.
He obviously is very good at his craft as a communicator, which is easier said than done.
Conversation & meeting people, is an exploratory dynamic... & while i feel I'm pretty good, I've said alot of dumb shit that I wish I didn't. I think we all have.
That said in managing his life, & doing quite well... navigating the pit falls of fortune, fame & power.
Quite well. Living well is definitely the most important intelligence/knowledge.
In that case, I'm not sure I wouldn't fuck it up on the way.
That's a type of intelligence that is more important than cognitive capacity or propositional type inteligence or capacity.
(I'd rather have the ability to determine what has real relevance/value in life and solve daily/existential problems that are hard to define in in real life, than a type of intelligence/capacity that can solve physics equations/ (or what not) that are usually associated with the term intelligence or knowledge).
TLDR
I think he's smarter overall than most people think.
