This month, “Marketplace Tech” is looking back at a movie that came out 10 years ago, but feels very current. Spoke Jonze’s 2013 film “Her” depicts a lonely divorced man played by Joaquin Phoenix who falls in love with something like an artificial intelligence chatbot voiced by Scarlett Johansson. Marketplace’s Meghan McCarty Carino spoke with Marco Dehnert, a doctoral candidate in communications at Arizona State University, about his research on the relationships between humans and machines. He said these relationships are becoming more common as AI advances.
