Drawing on current research in artificial intelligence, robotics, and the possibility of “downloading” human consciousness as a means of extending the human lifespan, Uncanny Valley charts the relationship between Claire, a neuroscientist, and Julian, a nonbiological human. As Julian is “born” over the course of the play---first his head, then an arm, then both arms and his torso, and finally his legs---Claire educates him in techniques of being as human as possible: mirroring people’s speech, engaging in small talk, playing a musical instrument. Her goal is to overcome the “uncanny valley” effect by which people’s initial fascination with a lifelike artificial human inevitably transforms into revulsion. Their deepening friendship and Julian’s growing “humanity” lead to the revelations of an unhealed sorrow in Claire’s personal life and, ultimately, the purpose for which Julian has been created. The play culminates in an unexpected encounter between them that tests their knowledge of each other and of their own natures. Uncanny Valley explores the painful divide between creator and creation, the inherent unpredictability of consciousness, and how we are redefining what it means to be human in the 21st century.
