Abstract
The saying “it from bit” conjures up the idea of a universe which is nothing more than information, a simulation running on a computer, or an amorphous collection of non-physical numbers from which solid reality somehow condenses. This idea makes for good science fiction stories and after-dinner conversations, but we are more likely to make scientific progress by treating information as a useful concept, just like energy, leaving aside the question of whether it is more or less real than matter.
