However, our intelligence will continue to grow. According to futurists, the improvement in human intelligence would ultimately require adding a computer interface to the human brain.
The human brain is a machine, albeit a complex one, so is a computer especially a supercomputer. The brain functions on three levels: biological, psychological and computational. The computer, on the other hand, functions essentially by the computational approach. The human brain, is linked to a mind and, therefore, is capable of thinking. Many researchers in artificial intelligence (AI) believe that a computer can be made to think as well, with the help of a computer program with the right inputs and outputs (Searle, 1990). However, Searle disputes this saying that computers, based on rules in the computer program, just manipulate symbols that are syntactic; therefore, “merely running the computer program is not enough to guarantee cognition.” Syntax of symbols and programs is only abstract and does not identify any physical phenomena whereas the domain of syntactic rules in the human brain is the sentence which is computed in combinations of fixed words as specified by the syntax. Also, more importantly, when uttered the meaning of the sentence is integrated with other information including semantic information from extra-linguistic domains such as co-speech gestures or the visual world. These steps are important for the listeners to interpret the language. Thus, in the case of a computer program, the computer which is the listener, is unable to interpret the language of the computer program which is only syntactic and abstract, and devoid of semantic framework. Therefore, computer programs are not the equivalent of nor do they have minds.
According to Searle, thinking is not analogous to formal symbol manipulation. Yet, he says he does not believe that thinking is a purely biological process. Notwithstanding the fact that advances in neuroscience
