It has always been difficult for contemporaries to recognise the peculiarities of their own epoch in which they live. Later on, after decades or centuries, it is much easier to analyse and explain things ex post in countless doctoral thesis and other scholar work. Nevertheless, those who here and now get at least some vague idea of what might be a distinguishing feature vis-a-vis history will surely enjoy the benefit of a more appropriate assessment of options and actions.

For example, in the 1960s the world saw the heydays of mechanical engineering, and in particular Germany had a strong reputation for construction and manufacturing of high quality machining tools. The automotive industries were booming, and a linear extrapolation of the near time expectations of those days to longer time scales resulted in utopian dreams of universal mechanical three-dimensional mobility by flying saucers available for everyone expected to become reality soon after the year 2000.
Nothing of that has happened. Instead, other big things are going on.
