In her 2011 book, "Alone Together: Why We Expect More from Technology and Less from Each Other," MIT Professor Sherry Turkle writes: "Technology is seductive when what it offers meets our human vulnerabilities. And as it turns out, we are very vulnerable indeed. We are lonely but fearful of intimacy. Digital connections and the sociable robot may offer the illusion of companionship without the demands of friendship. Our networked life allows us to hide from each other, even as we are tethered to each other."
