The desirable robot has been a trope in science fiction from Metropolis to the new film Ex Machina. American University professor Despina Kakoudaki (author of "Anatomy of a Robot") says watching actors play robots is a wish fulfillment -- imagining what it would be like to not feel emotions or deal with the messiness of the human body. I also talk with playwrights Mariah MacCarthy and Leah Nanako Winkler about their off-Broadway festival "Sex with Robots," which explores the dark desires behind an impossible fantasy.
