Here is what my last essay was, to give you an idea:

Technological Progress, a Step Backwards?
Isaac Asimov was a science-fiction writer from mid-nineteenth century who wrote many books about robots and other advanced technology. Many of his books, such as I, Robot and Robot Dreams, were about the ethics and the thought-processes of robots. Asimov presented ideas concerning what would happen in the distant future and the moral and social problems thinking robots would bring. However, that future was not so distant. In fact, my generation and its ever-growing technology will have to face the challenge of science and technology versus ethics. Despite the advantages of modern technology, its developments in the realms of genetic engineering and robotics infringe upon the ethics of the <?xml:namespace prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" /><st1:country-region w:st="on"><st1lace w:st="on">United States</st1lace></st1:country-region>.
Scientific advancements have made a positive difference in many lives. One major scientific development that has done this is the advance in the understanding in the human genome. For example, knowledge of the human genome has helped scientists discover how certain diseases, such as Down syndrome, work and how they might be treated. The human genome project has also helped doctors identify conditions of their unborn children and how they may be treated after birth. This progress has made many children live better lives. Advancements in robotics have also improved many lives. For instance, advances in robotics have allowed handicapped people to get around more easily with robotic limbs. In addition, some simple forms of robots have been created in computers and assembly lines to help make the work process easier and more efficient. However, even though these advancements have helped many people and made life easier and more enjoyable, they have both led to issues that will challenge our generation’s ethics.
While these advancements have bettered life, some contend that they neglect ethics. The human genome project and its development have brought up many ethical issues. For example, with the advancement in this field, a doctor is able to see and detect the sex and attributes of a baby before birth. Soon, however, doctors may be able to change these attributes of the unborn child, including changing the appearance or gender. This brings up the issue of whether parents should change these attributes of their child before birth just because they want a “perfect” child. Similarly, the advancements in robotics also bring ethical issues. By giving robots A.I., or artificial intelligence, we may be able to almost create life through robots. In addition, even though giving robots A.I. would make solving the world’s problems easier, it may also lead to rebellions and other uprisings due to the infallible, yet twisted, mind of a robot. While science advances through the years, it brings the ethical conflicts and problems with it.
The solution to each of these problems can be interpreted and thought out a number of different ways. I believe that the human genome alterations should only be made to help with birth defects, not with alterations of personal attributes. I also believe that artificial intelligence should not be added to robots, for the human mind can solve any problem necessary with enough time. However, if no action is taken by my generation to improve our moral science as well, we are doomed to a life lacking in ethics.
