I also think of him as a ten-year-old boy with access to infinite amounts of other people's money. Embarrassing stunts like "let that sink in" is the sort of thing my friends and I would have done at age ten thinking we were being awfully clever and witty, but no-one past the age of about fourteen or fifteen would still think that. And stuff like the Cybertruck is what you'd expect if you gave a ten-year-old (or Homer Simpson) some pencils and paper and said "draw your dream vehicle".
