The thinking of engineers and computer scientists is typically about the future. They envision answers to our questions and solutions for today’s problems that will be possible in the near future. Depending whether the emphasis is more on the solutions or on the problems, we talk of visions or challenges respectively. In Germany, we do not lack appropriate attempts. Some published examples show possibilities and weaknesses. To talk about visions is useful; it is better though to realize them. The technical and economic potential offered by computing is immense. We have just started to exploit it.
