Serial computers and their programs are very powerful tools used to perform tasks requiring the repetition of a number of well-defined operations where accuracy, reliability, and speed are important features. These information processing systems are very useful but not intelligent; the only element of intelligence in the whole process is the programmer who has analyzed the task and created the program. For an artificial system to be intelligent, it should at least be able to solve problems that humans find simple, trivial, and natural.
