This challenge, viz. the confrontation with the programming task, is so unique that this novel experience can teach us a lot about ourselves. It should deepen our understanding of the processes of design and creation, it should give us better control over the task of organizing our thoughts. If it did not do so, to my taste we should no deserve the computer at all! It has allready taught us a few lessons, and the one I have chosen to stress in this talk is the following. We shall do a much better programming job, provided that we approach the task with a full appreciation of its tremenduous difficulty, provided that we stick to modest and elegant programming languages, provided that we respect the intrinsec limitations of the human mind and approach the task as Very Humble Programmers. -- E. W. Dijkstra, The humble programmer
