Ginsberg, Matt: - Matt Ginsberg got a PhD in astrophysics from Oxford when he was 24. He quickly came to his senses, however, switching to artificial intelligence and teaching at Stanford for a decade. He's been on the front page of the New York Times and, surprisingly, was happy about it. He's been a political columnist and published playwright, and constructs crosswords for the Times. He has written about a hundred technical papers. And one novel.
