During the first stage of the electronic revolution change came in
discrete installments. Sure, the first people exposed to the telephone
were susceptible to dissonance and disorientation; many heard ghosts
and demons jabbering out of the receivers, but as a rule people were
given some pause between inventions, some time to adjust. Phone, film,
phonograph, radio, all had a sort of clear, well bounded existence when
they arrived on the scene. A Moore's law of sorts applied to inventions.
