On a Sunday afternoon in 2035, a man in Tokyo is consulting a robot as to what he should eat for dinner.
"It seems that you have a heavy feeling in your stomach today; I suggest fish and vegetables," the robot said, based on the man's health data retrieved automatically from a device he is wearing. "I would suggest ordering a cabbage from this farm, as it matches your preference for pesticide residue limits."
"Okay," the man says. Soon after the cabbage was delivered from the farm by drone, the robot installed a recipe data file to a cooking machine to prepare dinner for the man.
