Critical timeframe
A critical point is reached when information and technology become obsolete faster than the approximately 20-year timeframe in which the leadership of one generation is taken over by the next one. At that juncture the experience of the older generation is no longer all that helpful (Abraham Pais, 1997).
Need to rethink the concept of culture: What should be passed on from one generation to the other? And what is not worth passing on? And what do we in fact pass on?
