Thank you for sharing this. I always imagined him this way but a confirmation by who met him personally produces a nice feeling. By the way an idea just hit me: Stephen Wolfram probably has a great understanding of how does popular image of a person evolves and lives loosely dependent on their real selves: to me it feels like it's a lot like the cellular automata he described in "A New Kind of Science". We can hardly produce a reliable and concise quantification of popular sentiment surrounding a person but if we could the mechanics would probably be similar.
