At only 14 years old, Avatar is the most intelligent human known to us. Yet for all his intelligence, he doesn’t speak. He’s actually Autistic.
For that matter, we can’t get him away from the computer or his games. The best we can do is ask him a question. He’ll scribble the answer quickly, then return to his… whatever it is he does. There is a rumor going around that if he ever beats the games he’s working on, the world will most likely end.
