In Learning from Las Vegas, Robert Venturi makes his conclusion:

When Modern architects righteously abandoned ornament on buildings, they unconsciously designed buildings that were ornament. On promoting Space and Articulation over symbolism and ornament, they distorted the whole building into a duck. They substituted for the innocent and inexpensive practive of applied decoration on a conventional shed the rather cynical and expensive distortion of program and structure to promote a duck, minimegastructures are mostly ducks. . . . It is now time to reevaluate the one-horrifying statements of John Ruskin that architecture is the decoration of construction, but we should append the warning of Pugin: It is all right to decorate construction, but never construct decoration.
