I had not heard of LISP at 15, either. I already knew I loved programming, but what I was doing was rudimentary. I can't imagine how a teenager finds his or her way into such advanced programming. I personally need a formal computer science education for that. Patrick Collison is really impressive, and I had the fortunate chance to randomly meet him at a coffee shop (he probably doesn't remember me). He is a YC alum, having founded and sold Auctomatic. He later created and sold an iPhone app that was a locally compressed copy of Wikipedia. Very cool. http://collison.ie/ http://collison.ie/
