This is a rhapsody about AI. When AI grows to true artificial intelligence and can do any job more efficiently and perfectly than humans, what will be left for humans? Is it hell - AI sweeps all industries, causing unemployment, overproduction, and people have no consumption power at all? Or paradise - relying on AI to solve energy, unlimited supplies, human beings only have to enjoy, let us imagine. In this book, AI will not rebel and eliminate humans like Skynet. It will only efficiently solve problems raised by humans. I will promote the evolution of AI into the subsequent plots as soon as possible. I hope everyone will support me. I hope everyone will understand if the writing is not good for a newbie.
