Technological change is not additive; it is ecological. – apply the idea

Each member of the group first needs to explain the idea in his/her own words, and then he/she will apply the idea to discuss the selected technology. Explanations demonstrate a very good understanding of the ideas. The presenters are able to apply the ideas to discuss the technology and no improvement required. Below is the idea.

The consequences of technological change are always vast, often unpredictable, and largely irreversible.
What happens if we place a drop of red dye into a beaker of clear water? Do we have clear water plus a spot of red dye? Obviously not. We have a new coloration to every molecule of water. That is what I (Postman) mean by ecological change. A new medium does not add something; it changes everything. That is why we must be cautious about technological innovation. 
Example: In the year 1500, after the printing press was invented, you did not have old Europe plus the printing press. You had a different Europe. After television, America 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, and so on.
That is also why we must be suspicious of capitalists. Capitalists are by definition not only personal risk takers but, more to the point, cultural risk takers. The most creative and daring of them hope to exploit new technologies to the fullest and do not much care what traditions are overthrown in the process or whether or not a culture is prepared to function without such traditions. I say only that capitalists need to be carefully watched and disciplined. To be sure, they talk of family, marriage, piety, and honor but if allowed to exploit new technology to its fullest economic potential, they may undo the institutions that make such ideas possible. 
Example: It is clear by now that the people who have had the most radical effect on American politics in our time are not political ideologues or student protesters with long hair and copies of Karl Marx under their arms. The radicals who have changed the nature of politics in America are entrepreneurs in dark suits and grey ties who manage the large television industry in America. They did not mean to turn political discourse into a form of entertainment. They did not mean to make it impossible for an overweight person to run for high political office. They did not mean to reduce political campaigning to a 30-second TV commercial. All they were trying to do is to make television into a vast and unsleeping money machine. That they destroyed substantive political discourse in the process does not concern them.
