Introduction

Long-term forecasts are chronically difficult. It is unlikely that “revolutionary” events, such as the explosion of communication and interactive facilities that shape our current way of life, from social networking to international offshoring, could have been predicted 20 years ago with any degree of precision. Nevertheless, even though attempts to predict the future may, to a large extent, rely on extrapolations of current trends, these efforts may help to take stock of important developments and identify challenges arising from changes that we are likely to face.
