As our world simultaneously shrinks and expands through the growing abilities and applications of computers in our everyday lives, it seems that the role of the computer has been reversed. Before we knew that the computer only understood what we programmed it to understand; however, now the majority of our society is learning more from computers than they are able to input into it. As stated, it only seems that the roles are being reversed, because somewhere far down at the beginning of the line someone is programming the computer.

However, a transition is occurring among computer programmers, as they attempt to create machines that learn rather than machines that must be programmed. It has become the hope of many engineers that the "mechanisms of human thought could be precisely modeled and simulated on a computer".

This is known as Artificial Intelligence. Artificial Intelligence, or AI, since its conception, has grown from a dozen researchers, to thousands o

Concluding with Economic uses: Large financial institutions have used ANN's to improve performance in such areas as bond rating, credit scoring, target marketing and evaluating loan applications. These systems are typically only a few percentage points more accurate than their predecessors, but because of the amounts of money involved, they are very profitable. ANN's are now used to analyze credit card transactions to detect likely instances of fraud.

A back-propagation ANN, conversely, is trained by humans to perform specific tasks. During the training period, the teacher evaluates whether the ANN's output is correct. If it's correct, the neural weightings that produced that output are reinforced; if the output is incorrect, those weightings responsible are diminished.

With all that the computer is learning now a new question arises: How long before a computer can learn to understand and execute the attributes of a good sense of humor? It is believed that the theory of AI has existed long before recorded, but was not made conceivable until the invention of the electronic computer in 1941 (Dreyfus p. 6). Since then many scientists and engineers have been working on a way to make the computer more human.

This includes such "simple" machines as intelligent chess boards and other programs for elementary games. In the mid 1960"s, however, Marvin Minsky created and interactive computer program that many believed to be Artificial Intelligence. Though Minsky was even doubtful of his achievement another scientist, Joseph Weizenb
