 My book is about when robots rule the earth. So, you might think it's relatively speculative, but I decided to take a standard scenario that's common in futurism and science fiction of a certain kind of artificial intelligence that would be as smart as people and work out what that world would look like. So, I spent four years in great detail taking each part of this world and just trying to apply standard consensus academic results to ask, what would this world look like? And so, I describe a world in terms of its economics and its physical infrastructure and its families and its romance and its jobs and its cities and its wars and its conflicts and I work out as best I can a detailed analysis of what would happen in this particular kind of world. And I say it's like science fiction except there's no plot and there's no characters and it all makes sense. Because I've always wanted something like that, an analysis of the future that actually makes sense if you think about it. And so, that's what I produced. My book is called The Age of M, Work, Love and Life, When Robots Rule the Earth.
