Book excerpt: The world is experiencing unprecedented rapidity of change, originating from pervasive technological developments. This book considers the effects of such rapid change from within computing disciplines, by allowing computing educationalists to deliver a considered verdict on the future of their discipline. The targeted future, the year 2020, was chosen to be distant enough to encourage authors to risk being visionary, while being close enough to ensure some anchorage to reality. The result is a scholarly set of contributions expressing the visions, hopes, concerns, predictions and analyses of trends for the future.
