"I think there are some kids who got the idea that it may be a little cooler to know stuff and to read and to learn. If watching me on TV convinces some kid that they've got some future in knowledge, that would be very rewarding to me."
And you know, I read an article the other day that said chess was exploding in popularity among kids, so who knows--maybe the geeks shall rise again! :D
Of course, we all know geeks have always been cool. :D
