There's no way to create that book without doing the calculations from each tick to the next. So when you put it into the computer, it's just repeating the calculations done the first time in the creation of the book. I do think your broader point about the importance computation is correct nonetheless. Though it gets more confusing when you start thinking about what computation actually is, or about the possibility of Boltzmann brains ( http://en.wikipedia.org/wiki/Boltzmann_brain http://en.wikipedia.org/wiki/Boltzmann_brain )
