Transportation is a great example. It is much easier to move a robot through the world than it is to build a robot that can interact with it. Over the last decade, significant advances in algorithms and hardware have made it possible for us to envision a world in which people and goods are moved in a much safer, more convenient way with optimized fleets of self-driving cars.
