First, that we always pay a price for technology; the greater the technology, the greater the price
Second, that there are always winners and losers, and that the winners always try to persuade the losers that they are really winners
Third, that there is embedded in every great technology an epistemological, political or social prejudice. Sometimes that bias is greatly to our advantage. Sometimes it is not. The printing press annihilated the oral tradition; telegraphy annihilated space; television has humiliated the word; the computer, perhaps, will degrade community life. And so on.
Fourth, technological change is not additive; it is ecological, which means, it changes everything and is, therefore, too important to be left entirely in the hands of Bill Gates.
And fifth, technology tends to become mythic; that is, perceived as part of the natural order of things, and therefore tends to control more of our lives than is good for us. .... When a technology become mythic, it is always dangerous because it is then accepted as it is, and is therefore not easily susceptible to modification or control.
