For all of human history, with the exception of thoughts about some other animals and the idea that there might be forms of intelligence we cannot perceive, humanity has been alone. In myth and religion, we have imagined other forms of intelligence. In science fiction, we have stretched our imagination to envision alien minds. While aliens would in a sense be humanity's sibling, AI is a child. We have never had something else to talk with other than ourselves, and now we hold a mirror to ourselves1.
