The prospect that we may someday have intimate sexual relationships with robots has captured the popular imagination. John Danaher, editor of Robot Sex: Social and Ethical Implications, asks what the future holds for this technology and how we should feel about it in terms of economic and social consequences, the effect on sex workers, marriage, gender relations and politics. Includes a Q&A with Ewa Drygalska, who has written on VR and pornography.
