'Every so often, it becomes necessary to clear up a misperception. When I make mistakes, I own up to them. I stopped reading Dintersmith's book because I concluded that the underlying message was actually bashing public schools for being “obsolete” (Bill Gates’ favorite term). I concluded that Dintersmith was promoting himself as an educational guru based on his business experience, and we have had too much of that already. We don’t need more business and corporate leaders—with no experience in schools—redesigning American education. Dintersmith began emailing and calling. He wanted my endorsement. I said no. He sent me a video based on the book. I didn’t watch it. He kept emailing. He wanted to meet. I didn’t have time. Maybe he is a good man, and I am being unfair. But I am not a member of his fan club.'
