Soon, it will be impossible to tell the difference between AI and a real human, especially in a text format. I'm convinced people won't read books written by humans anymore. A fictional book will be created on the fly for the reader, like they are playing D&D or something, basically role playing where any outcome is possible. Anything, from the reader being the main character to the reader only suggesting the basic genre of the book and letting AI create a one of kind story. Soon this will be the case for images, then Music, and finally video.
