Andy Hertzfeld, the first Mac programmer ever, was recently at Google's New York City offices (which they keep very dark it would seem). He was there to give a talk about his book, Revolution in the Valley (which is based on his website Folklore.org). Oddly enough, the talk found its way onto Google Video (it is embedded in this post, or you can watch it here).
The talk is a little over an hour long. Enjoy!
