The following quote is from Steven Levy’s new book, Facebook: The Inside Story.

“We’ve actually built an AI that’s more powerful than the human mind and we hid it from all of society by calling it something else,” Harris says. “By calling it the Facebook News Feed, no one noticed that we’d actually built an AI that’s completely run loose and out of control.” Harris says that using the News Feed is like fighting an unbeatable computer chess player—it knows your weaknesses and beats you every time.”
