Futuristic interfaces are supposed to solve problems and make life easier. What good are they—besides being eye candy—if the future around them is picture-perfect already? The Microsoft video takes that conceit of perfection and carries it so far that the concepts begin to look ridiculous: You can pick out all kinds of clever touches, such as the way the images on a computer screen can be dragged off screen to become holograms—and then can be controlled with gestures. But by that point, we’re way off in future land, where none of these clever touches feel rooted in life. They don’t address problems we understand.
