The search for a workable theory for at least human consciousness, and the work that's going on in machine learning. I love te back and forth from my attention as i read your book being given to also trying to solve maybe the thing that didn't really happen. And you follow, what i think is now, in my second reading, a really brilliant way. You let the book unfold basically the days of the week. But i'm not going to say too much more about that. I want people to read it and follow along.
