However, my strongest personal response to the show has been an unex- pected realization that the ethical issues AI poses in Westworld will likely be the foremost issues the field of radiology faces during my career. WHERE WILL AI TAKE US? In Westworld, the AI incorporated into “host” robots has advanced to the point of passing the famed Turing test. Westworld triggers Visitors to the titular theme park cannot distinguish these artificial beings from reflections about actual humans. Today, in the real world, advancements in deep learning are allow- ing AI to accumulate new information and radiology’s future understanding at a rate that humans can- not match.
