He just reminded me of a 'modern day Einstein'. I understand the main point of the article was that Einstein's genius took a lot of hard work, same as the kid. They do have a lot of similarities in their process of acquiring knowledge and understanding.
besides, obtaining a PhD, even at an early age, doesn't make you a genius... well, at least not an Einstein-like genius.
I look at it through the way they both think, how they both process information. He's a pretty interesting kid.
