Google Maps is the world’s top navigation app and in February it will turn 20 years old. It’s got new generative AI features, and a nimbler Street View camera that will help it map new countries. Street View cameras have taken billions of images and mapped millions of miles since Google co-founder Larry Page first had the idea for Maps. Now, it’s in 250 countries. CNBC got an exclusive look at the Street View service center and asked the head of Maps about data, privacy, traffic and AI.
