Will humans always be superior to machinesThis statement actually consists of a series of three related claims: (1) machines are tools of human minds; (2) human minds will always be superior to machines; and (3) it is because machines are human ’tools that human minds will always be superior to machines. While I concede the first claim, whether I agree with the other two claims depends partly on how one defines "superiority," and partly on how willing one is to humble oneself to the unknown future scenarios.(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.(42) And, the claim that a machine can be an end in itself, without purpose or utilitarian function for humans whatsoever, is dubious at best, since I cannot conjure up even a single example of any such machine.(43) As for the statement’s second claim, in certain respects machines are superior. We have devised machines that perform number-crunching and other rote cerebral tasks with greater accuracy and speed than human minds ever could. However, if one defines superiority not in terms of competence in performing rote tasks but rather in other ways, human minds are superior. Machines have no capacity for independent thought, for making judgments based on normative considerations, or for developing emotional responses to intellectual problems.(44)Up until now, the notion of human-made machines that develop the ability to think on their own, and to develop so-called "emotional intelligence," has been pure fiction. Besides, even in fiction we humans ultimately prevail over such machines—as in the cases of Frankenstein’s monster and Hat, the computer in 2001: A Space Odyssey. Yet it seems presumptuous to assert with confidence that humans will always maintain their superior status over their machines. In other words, machines will soon exhibit the traits to which we humans attribute our own superiority.(45) And insofar as humans have the unique capacity for independent thought, subjective judgment, and emotional response, it also seems fair to claim superiority over our machines. Besides, should we ever become so clever a species as to devise machines that can truly think for themselves and look out for their own well-being, then query whether these machines of the future would be "machines" anymore.[A] Recent advances in biotechnology, particularly in the area of human genome research, suggest that within the twenty-first century we’ll witness machines that can learn to think on their own, to repair and nurture themselves, to experience Visceral sensations, and so forth.[B] The statement is clearly accurate insofar as machines are tools of human minds.[C] In sum, because we devise machines in order that they may serve us, it is fair to characterize machines as "tools of human minds."[D] It’s hardly surprising that human-made machine can do the most works that belong to human before.[E] In fact, it is because we can devise machines that are superior in these respects that we devise them--as our tools—to begin with.[F] When we develop any sort of machine we always have some sort of end in mind—a purpose for that machine. 45()
