On a desk at his studio in Somerset House in central London, artist Lawrence Lek keeps a Buddha bobblehead. The protagonist of his latest film, an AI “carebot” therapist designed by the fictional Farsight corporation to treat other AI creations — self-driving cars, surveillance programs — is named after the Buddhist goddess of compassion, Guanyin. A series of sketches depicting the character’s evolving design are pasted on a wall, culminating in the figure of a friendly toy robot. “Farsight would want to make a cute, appealing avatar for their full-surveillance empathy-AI system,” Lek says drily.
