A new gold rush? How AI is transforming San Francisco

On a sunny day in San Francisco, along the city's waterfront, families dived into the wacky world of artificial intelligence inside the Exploratorium museum. Visitors made shadow puppets for AI to identify, used AI to generate songs, asked chatbots questions and faced off with AI in a game in which players tried to draw images that only humans would recognize. A giant robot hand moved around and people peered into a video game chip. They jotted down their hopes and worries about AI on cards displayed in the museum. Hope: AI will cure cancer.
