Spot on . . . to borrow from Thoreau, &#x27;&#x27;the mass of men lead [sex] lives of quiet desperation&#x27;&#x27;.  (As a man, I&#x27;m more familiar with the male perspective.)  I think even a crude early version of a sex robot that males could interact with at home would revolutionize society with all sorts of consequences to romantic relationships, birth rates, social development, and so on.  Combine the physical manipulations with AI and VR and I think it will be as or more important than developments like self driving cars and 1 hour drone deliveries.
