PART II: Essay. Answer each question below in the space provided. Each question is worth 20 points.

21. The five canons of the ACM code of Professional Conduct are:

1. An ACM member shall act at all times with integrity.

2. An ACM member should strive to increase his competence, and the competence and prestige of the profession.

3. An ACM member shall accept responsibility for his work.

4. An ACM member shall act with professional responsibility.

5. An ACM member should use his special knowledge and skill for the advancement of human welfare.

From your reading of the Cuckoo's Egg by Cliff Stoll, and assuming that Stoll was a member of the ACM or a similar professional organization, give your opinion of the ways in which he adhered to, or violated, the canons of the above code in his search for the intruder into the Berkeley computer system.

Canon 1. He acted with integrity by sticking to the task to which he was assigned.

Canon 2. He certainly had to extend his own competence to understand the problem he was undertaking.

Canon 3. He took responsibility for his work by being willing to go to court to prosecute the intruder.

Canon 4. Difficult to judge.

Canon 5. He certainly protected "human welfare" by trapping a person who was attacking the "law and order" of international espionage.

22. A team of artificial intelligence scientists has invented an automatic speech-recognition device and voice-response system that can be used economically to serve customers of automated teller machines for most banking services. Great effort is made to convince customers that they are conversing with a real person. In fact. in case of system failure, a human substitutes for the voice response system and follows the same protocols and rules as the automated system. No capability is included to permit the customer to know whether the conversation is with the automated device or a human.

Respond to the following opinions regarding the potential ethical behavior on the part of the purveyors of this system:

(a) The inventors are marketing a device specifically designed to deceive the public and take no responsibility for the social implications of their product. This is unethical behavior.

Disagree. The inventors are designing a friendly man-machine interface which is more likely to be accepted by customers than a totally artificial system. The whole goal of AI is to imitate human systems to better serve the public. In many ways all computers imitate human action; imitation is not equivalent to deception.

The "Turing Test" distinctly sets the goal of building systems which imitate humans.

The social implication of making a computer simulate a human is non-negative.

Like Nobel, an inventor often has no control over the uses of his invention; if there is a problem here it is in the use of the system not its design - unless the user is purposely kept unaware of negative social implications.

(b) Any bank which uses this device is a party to deception and fraud. This is unethical behavior.

Disagree. So long as the bank provides a service which is beneficial to the customer, and is not socially threatening or disruptive, there is no unethical behavior.

Bonus Question: Worth 10 points.

23. What is wrong with the following statement?

John Napier made his two biggest contributions toward reducing wear and tear on mathematicians. In 1594 he invented logarithms, and in 1617 he improved [mathematical tables] by applying his logarithms to blocks of wood. By applying them to blocks of wood shaped like rulers, two rulers could be laid side by side and the answers read directly. These rods of wood, called "Napier's Bones" were improved rapidly.

Napier never linked his "bones" with logarithms. Slide rules were invented by Oughtred after Napier's death. Slide rules were never called "Napier's Bones". The "Bones" were not shaped like rulers. Napier announced his discovery of logarithms in 1614.
