 I want to ask you, looking back now six years later, is there anything you would change about the book? How do you think things have come since then? Where are we in this space? Well, it's the old joke when somebody turns in their dissertation, they say, I wrote a 500-page dissertation because I didn't have time to write a 200-page dissertation. So when you look back at anything you wrote a while ago, you're like, where the heck was my editor?
