Preface
To write this thesis I used an Apple laptop computer that gave me access to a variety of cognitive tools such as a word processor, a PDF reader, and the internet. A mere twenty years ago I would not have had the benefit of these technologies, either because they did not exist, or because they were not yet ready for mass adoption. To me this illustrates how fast technology is changing our lives. The pace at which technology is developing accelerates at an exponential rate (Kurzweil 2005). Between the development of agriculture in the Fertile Crescent and the invention of the wheel lies a period of four thousand years. Between the invention of the catapult and the invention of the cannon there is a period of two thousand years, and the period between the development of paper and the movable type printing press is a thousand years. The invention and mass adoption of technologies such as cars, airplanes, computers, and the internet all took place in the past century. I believe that the accelerated development and the current convergence of new technologies will greatly benefit mankind. For instance, future technologies will have the potential to stop the environmental damage that threatens our planet, help to eliminate poverty, and will successfully combat the effects of old age. However, while the potential benefits of technology are considerable, the risks that flow forth from misuse and abuse are also substantial. My primary motivation for writing this thesis is as follows: I feel that we have reached a point in time where the pace of technological development is so fast, and its potential impact on society so significant, that the introduction and subsequent use of disruptive future technologies should be subjected to a closer scrutiny than so far takes place. In my opinion society as a whole should become more aware of the policy issues surrounding new technologies. For this thesis I have chosen to focus on specific policy issues related to artificial intelligence technology. In the summer of 1956 the Dartmouth College hosted the first conference on artificial intelligence. Now, fifty years later, the use of artificial intelligence is widespread within our society, despite the fact that artificial intelligence acting on the level of a human being has not yet been achieved. One area in particular that can benefit from the application of artificial intelligence is surveillance. Using artificial intelligence technology for sur-

Preface
veillance purposes can increase national security and public safety. However, this also places additional power into the hands of the government. It is therefore important to give careful consideration to the ways in which governments use surveillance technologies, and how these technologies may change the balance of power within society. The great statesman and third president of the United States, Thomas Jefferson, once said: “the price of freedom is eternal vigilance”. In this time of high technology I feel Jefferson’s statement is even more relevant. The power of technology can quickly distort the balance of power between the populace and their elected leaders, or may have other unwanted or unintended consequences. Therefore, it is essential to remain vigilant when it comes to the use of powerful new technologies for surveillance purposes. By keeping a close eye on the use of new technologies we may ensure that we reap their benefits, while avoiding possible negative effects. I hope that by writing this thesis I will have contributed to this goal. Bart W. Schermer Leiden, January 2007
