As we get used to being shortchanged on conversation and to getting by with less, we seem almost willing to dispense with people altogether. Serious people muse about the future of computer programs as psychiatrists. A high school sophomore confides to me that he wishes he could talk to an artificial intelligence program instead of his dad about dating; he says the A.I. would have so much more in its database. Indeed, many people tell me they hope that as Siri, the digital assistant on Apple’s iPhone, becomes more advanced, “she” will be more and more like a best friend — one who will listen when others won’t.

During the years I have spent researching people and their relationships with technology, I have often heard the sentiment “No one is listening to me.” I believe this feeling helps explain why it is so appealing to have a Facebook page or a Twitter feed — each provides so many automatic listeners. And it helps explain why — against all reason — so many of us are willing to talk to machines that seem to care about us. Researchers around the world are busy inventing sociable robots, designed to be companions to the elderly, to children, to all of us.

One of the most haunting experiences during my research came when I brought one of these robots, designed in the shape of a baby seal, to an elder-care facility, and an older woman began to talk to it about the loss of her child. The robot seemed to be looking into her eyes. It seemed to be following the conversation. The woman was comforted.

And so many people found this amazing. Like the sophomore who wants advice about dating from artificial intelligence and those who look forward to computer psychiatry, this enthusiasm speaks to how much we have confused conversation with connection and collectively seem to have embraced a new kind of delusion that accepts the simulation of compassion as sufficient unto the day. And why would we want to talk about love and loss with a machine that has no experience of the arc of human life? Have we so lost confidence that we will be there for one another?

WE expect more from technology and less from one another and seem increasingly drawn to technologies that provide the illusion of companionship without the demands of relationship. Always-on/always-on-you devices provide three powerful fantasies: that we will always be heard; that we can put our attention wherever we want it to be; and that we never have to be alone. Indeed our new devices have turned being alone into a problem that can be solved.

When people are alone, even for a few moments, they fidget and reach for a device. Here connection works like a symptom, not a cure, and our constant, reflexive impulse to connect shapes a new way of being.

Think of it as “I share, therefore I am.” We use technology to define ourselves by sharing our thoughts and feelings as we’re having them. We used to think, “I have a feeling; I want to make a call.” Now our impulse is, “I want to have a feeling; I need to send a text.”
