The book´s role has diminished because of all the other actors; it's no longer king of subject. We owe a lot to the book, the assembly line of mass production, for example, comes to us from the book, from the printed line where things move along and happened one at a time. But the assembly line has changed, it is no longer one thing at a time, but wherever possible everything at once. Forty or fifty operations happening at the same time, controlled and synchronized, exactly by pre-set tape.
