But on a personal note:

There were complications during the creation process, and I can only take claim for a few of the chapters. The chapters I wrote were dealing with multiple pre-existing AI's, and while talking with some of the developers of them, I was pleased at how receptive they were to recommendations. That however, created the issue that the code base would keep changing. Keeping updated in the code was a real night mare.
But kudos to the AI developers for constantly improving and moving forward. And kudos to Curtis Bennett, for grabbing the remnants of the book when I no longer had the time to work on it and finishing it. I can't wait to read what he put into it. :D
