I very much agree with the emphasis on actionability. But what is it about a physical artifact that makes the knowledge it contains actionable? I don’t think it can be simplicity alone. Suppose I record the trajectory of the moon over many nights by carving markings into a piece of wood. This is a very simple representation, but it does not contain actionable knowledge in the same way that a textbook on Newtonian mechanics does, even if the textbook were represented in a less simple way (say, as a PDF on a computer).
