Something that struck me from the reading is the claim that a drawing cannot be edited. I thought that viewing any interaction with the physical media as additive is a very unique lens. The example given, about the erasing of a pencil mark, expresses this notion cleanly. I also thought the idea that a drawing needs to be perceived was interesting as well. A computer aided program, with initial conditions given by a human is then definitionally a drawing. It does beg the question: if a human designs a machine to design a machine to draw something, is it still a drawing? In other words, to what extent can the human be removed from the process for the output to still be considered a drawing? The idea of an anti-definition seems to hint that the answer is not binary.
