He has a kind of funny gay-ness to his voice, which really doesn't sound like the rational aura of Ti. And I also don't see him being a really random kind of kid like an Ne would be, so that coupled with his whole vision for the future seems like INTJ.
He looks so much like my brother--same age and hair + similar facial structure--that it's kind of surreal. Anyway, the most recent video makes me even more convinced that he's an ENFJ. The only other types I would really consider are INFJ and ENTP.
