Digital Stimulation considers the subject of intimacy, including sexual intimacy, between humans and machines, both in the imagination and in reality. In fiction and in fact, social robots are frequently gendered as women. It is therefore important to address their potential to reinforce, or perhaps to reinvent, existing attitudes and expectations about gender, including nonbinary and transgender identities, as well as race, class, disability, and other aspects of identity. This book provides an overview of the history of robots as depicted in popular culture, especially science fiction, as well as an overview of the history of sex toys, including blow up dolls and lifelike sex dolls. This invites an examination of the current and ongoing development of robots designed explicitly for intimate engagement with humans. The book explores positive (and often overly optimistic) attitudes, as well as negative (and often overly sensational) attitudes about the potential impact of robots and artificial intelligence. Finally, Digital Stimulation considers the possible ways in which future robot design might consciously disrupt the limitations of a binary system of gender, sex, and sexuality.
