Many roboticists and computer engineers seem to think so, because they're always trying to make their creations more human.
Take Solo, the "emotional radio", for example. A wall-mounted device that resembles a large clock, it features a liquid crystal display at its centre. When you approach it, the pictogram face shows a neutral expression.
But it then takes a photo of your face, a rod or antenna on the side cranks into life, and the LCD display indicates that it's thinking.
