The combination of Wolfram's awkwardness and intelligence/accomplishments results in what seems like hubris, but I think he is just trying to state things plainly. In this instance the "left to me" phrase simply means this is what he is now working on, not that he is the only one to fix dumb ol' Turing's mistakes. And he mentioned exactly how Turing "got distracted" in the next question: Turing jumped from project to project. This was something Wolfram described as a sometimes enviable trait. He's not disparaging the guy.
