Hiroshi Ishi­guro has spent a lifetime in pursuit of the perfect robot. He has modeled his creations on those closest to him — his wife, his child, himself — but he admits to feeling lonely while surrounded by his family, both human and inhuman. At Wired, Alex Mar unravels the depths of Ishi­guro’s passion for robots, and what he means when he tries to make them lifelike. However, Mar finds that after a lifetime of considering what it means to be human, Ishi­guro may not truly understand the basics of human interaction himself.

He has spent a lot of time talking to himself through his androids, testing them, imagining their effect on other ­people. Hiroshi (who by now has asked me to call him by his first name) tells me he’d like to record himself saying “I love you” and then program an android to repeat it back to him in a female voice. He is kidding when he says this—but maybe it’s another of his half-jokes. At the very least, he believes the need for such an exchange exists. It would be, he says, “a real conversation.” A conversation with himself.

“A conversation is a kind of illusion,” he says. “I don’t know what is going on in your brain. All I can know is what I’m thinking. Always I am asking questions to myself, but through conversations.” Over the years of operating his androids, communicating through them or with them, he has found that he isn’t really concerned about the other person’s thoughts. “Always I am thinking of myself. I need to understand your intention, but it is not a priority. Before that, I want to make clear something in my brain. Otherwise, what is the motivation to talk?”

In other words, he can only imagine using conversation with others as a means to better understand himself—and nothing is more pressing than that. He turns to the conversation the two of us are having. “We don’t know how much information we are sharing,” he tells me. “I am always guessing, and you are always guessing, and through our conversation patterns, we can believe that we exchange information. But I cannot access your brain directly.

“What is ‘connection’?” he asks. “Other person is just a mirror.”
