“‘Clearly this is not a biological dog,’ my husband said. He asked whether I had realised that the red light beneath its nose was not just a vision system but a camera, or if I’d considered where its footage was being sent. While I was away, he told me, the dog had roamed around the apartment in a very systematic way, scrutinising our furniture, our posters, our closets. It had spent 15 minutes scanning our bookcases and had shown particular interest, he claimed, in the shelf of Marxist criticism.”
