(41) After all, would any machine even exist unless a human being invented it Of course not. Moreover, I would be hard-pressed to think of any machine that cannot be described as a tool. Even machines designed to entertain or amuse us—for example, toy robots, cars and video games, and novelty items—are in fact tools, which their inventors and promoters use for engaging in commerce and the business of entertainment and amusement.
