Sexbot-induced social change (SISC) is on the horizon. SISC will influence a broad spectrum of social structures. This chapter focuses on one significant area: the nature of marriage. It makes three predictions. Prediction One: The adoption of Sexbot technology will disentangle the association between sexual intimacy and marriage, leading to higher quality marriages. Prediction Two: The adoption of sexbot technology will lead to the normalization of non-exclusive relationships as the dominant relationship structure. Prediction Three: Legal marriage institutions will be reformed to allow individuals to determine the nature of their own marriages free from state interference.
