He's just realistic. 99% of people are "idiots" by that definition. Twitter and the press are full of people who take themselves really seriously but turn out to be total idiots upon further scrutiny. I think it's undeniable, however, that he's really good at what he does. Spotify deal aside, wouldn't have 9 million subscribers otherwise.
thats where his skill as a conversationalist comes in. he speaks well especially to the common man. i do not think, personally, he is very intelligent or 'smart' but in terms of what he does he is. hes often incorrect about things he talks about, but it doesnt matter in terms of entertainment. realistic is too general of an assumption, common is more apt. he is great at what he does, but i dont see him as an authority on much (where i think many others do)
