I post on https://www.goodreads.com/. Today, when I logged on, there was a recommendation posted for me - by Goodreads, not by an individual.
It read: Because you enjoyed For the End of Time - The Story of the Messiaen Quartet
You might enjoy:
At first I thought, wtf. But then I thought I probably might enjoy reading it. I just wondered where the recommendation came from. I doubt that a human being was behind it, so that leaves a computer. Are they developing computers with senses of humor?
