If the last 50,000 years of man”s existence were divided into lifetimes of approximately 62 years each, there have been about 800. Of these 800, fully 650 were spent in caves. Only during the last 70 has it been possible to communicate effectively from one life time to another – as writing made it possible to do. Only during the last 6 lifetimes did masses of men ever see a printed word. Only during the last 4 has it been possible to measure time with any precision. Only during the last 2 has anyone anywhere ever used an electric motor. And the overwhelming majority of all the material goods we use in daily life have been developed within the present 800th lifetime.
[Alvin Toffler - 1970]
