Fifteen years ago (I remember the apartment where I had this thought), it occurred to me that time was running out to write an authentic novel. Soon, computers would generate whole stories in an endless variety of styles, and even if future authors would hand write a book from start to finish, they would likely have been influenced by other artificial writing at some point. Readers would be unable to emotionally connect with authors due to the nagging awareness that the text might have been fully or partially generated by an unthinking, unfeeling machine.
Though I try, I fail to think of a comparable scenario in our past, at least as relates to language. You can look around whatever room you are in and try to identify an object that was made by human hands rather than a factory process. That's a fact that always makes me a bit sad. I think we're headed in a similar direction with the language we consume. Craftsmanship falls by the wayside, and our world loses even more of the human touch that connects us with one another.
