The speaker asserts that machines will always be inferior to human beings for they are, after all, tools made by human and operate according to human will. In my view, this claim, though having its merits to some extent, turns out to be another human-centric view in the scientific realm. Based on the current study of artificial intelligence, it seems to me entirely possible that, machines will be able to feel, think, and act independently from human beings in the future.

In fact, human beings are never sure of his unchallenged superiority to machines. Since the human civilization entered the era of mass production, machine has always been the symbol of the ever-increasing productivity of an industrialized world. Their presence is everywhere: airliners flying over head, whining tractors in the fields of California, automobiles running out of Ford's factory, etc. Machine has provided us excessive material richness which is never conceived before. What humans are most proud of, of course, is that however powerful and productive a machine can be, it is always under human control and never shows any disobedience to human will. Human, through using those wonderful inventions, no longer need to feel sorry for his limit of physical strength. However, since the very beginning of the industrial revolution, men has been worrying about whether these mighty machines will one day turn against us. In spite of all of the benefits machines have brought us, they are made by humans and can run out of control.

Actually, the so-called human superiority to machine is continuously declining. Now, at the threshold of a brand new information age, machines have evolved into ever more complex form with the help of information technology. Much progress has been made, in making machines that resemble human in some respects. These machines, typically referred to as humanoid, can talk and even play tennis with different people. They are no longer oddly shaped robots seen by the car assembly lines but can understand human language and feelings and some go so far as to imitate human expression. When these humanoid machines interact with humans, they respond automatically without human orders, though still monitored by preset programs. Not to mention their calculating ability and physical power which already far exceed human limits, the machines are catching up in terms of real intelligence.

In my opinion, human beings will ultimately lose control of the machines. According to Moore's law, which describes the relentless exponential improvement in digital technology with uncanny accuracy, desktop computers will have the same processing power as human brains by the year 2029. If the study in artificial intelligence continues to develop at the current exhilarating speed, it won’t be long before scientists finally create machines that are more human than human. By that time, who can confidently say he is still superior to all the machines?

In sum, the speaker’s assertion is based on the fake confidence of human beings. AI scientists still need to go a long way towards the goal of realizing real intelligence in machines and may face countless obstacles. But don’t forget that many things one deems to be commonplace today are beyond his forefather’s wildest imagination. Humans cannot always be superior to machines.
