Editing as we know it today employs both the heart and the mind. Perhaps for some non-fiction books, a robotic editor or some software program will be able to improve upon a writer’s work, but I doubt that any technical discovery can ever replace the human spirit. How an editor feels upon reading a book and how that translates into his or her critique will ensure their continuing employment. With the growth of self-publishing, we’ve seen too many books that have reached the public without being edited with disastrous results. The reading public has noticed and has become twice shy about self-published books. Because of this problem, I forsee a growth in this part of the industry.
