In the book's first half, devoted to robots, Turkle gives out toys like the Tamagotchi, Furby, and Zhu Zhu robotic hamster(仓鼠)，then explores children's deep attachments to the creatures and assessments of whether they are alive. Such quasi­pets set the psychological stage for what Turkle is really worried about: robot lovers. One woman even says that if a robot acted like it cared, she'd trade in her boyfriend.

　　The book's second half explores the “network”—instant messages, social networks, confessional websites, and the like—and how it reshapes the self. Fifteen­year­olds send and receive close to 6，000 messages a month.“They communicate all day but are not sure if they have connected.They develop friendships on social networking sites and then wonder if they are among friends.” In texting, a typical question is“Where are you？”， not an open­ended one like “How are you？” Just as robots produce confusion about whether one is alone or with another, Turkle sighs.

　　“We_are_connected_to_each_other,_but_strangely_more_alone.”

　　“What can't be denied(否认) is that technology, with all its faults, makes life a lot easier. It allows us to get in touch with more people in less time; it can make conversation simple—no small talk required. But are any of those feelings face­to­face setting? Online, you can ignore others' feelings. In a text message, you can avoid eye contact. A number of studies have found that this generation of teens is becoming unconcerned. That doesn't spell disaster, but it does mean we might want to start thinking about the way we want to live. We've gone through terribly rapid change, and some of these things just need a little sorting out.”Turkle says.
