I am somewhat confused about his Ben Schneiderman’s distinction between a tool and something that is mimicking the form of a human or animal. He says that tools don’t mimic a human or animal but instead enhance them but this just doesn’t fit so perfectly as I am thinking about it. He says a plane is not mimicking a bird, and physically he is right. But looking at it in a more broad sense, a plane is mimicking a bird from the point of view of the flightless human being. So, I think it is reasonable to say that birds were likely part of what sparked the quest for human flight. Based on these musings, I think I would like to probe further about the relationship between something that mimics and bird or animal and something that is considered a tool.
