From Neil Postman:
Technological change is neither additive nor subtractive. It is ecological. … One significant change generates a total change. If you remove the caterpillars from a given habitat, you are not left with the same environment minus caterpillars: you have a new environment … In the year 1500, fifty years after the printing press was invented, we do not have old Europe plus the printing press. We had a different Europe. After television, the United States was not America plus television; television gave a new coloration to every political campaign, to every home, to every school, to every church, to every industry.
