The Age of Spiritual Machines

"At the start of the book, Molly is a 23-year-old woman who has little understanding of the concepts that are discussed in the book, yet has an enigmatic (sometimes romantic) interest in the author, which keeps her interested. By the time the book reaches Part III, Facing the Future, Molly has somewhat of a grasp on all these concepts. It is during Part III that she physiologically and technologically evolves (as predicted by the author) as the years go by, to the point that by the year 2099 (the farthest point in the author's scope), she has shed all biological matter and has become a dynamic, conscious sub-entity within a larger, singular entity, all within a machine (a Spiritual Machine, as it were). "Molly" has become so dynamic, in fact, that she is (in her words) ready to do anything, or be anything, you want or need."
