" The intellectual ethic of a technology is rarely recognized by its inventors. They are usually so intent on solving a particular problem or untangling some thorny scientific or engineering dilemma that they don't see the broader implications of their work. The users of the technology are also usually oblivious to its ethic. They, too, are concerned with the practical benefits they gain from employing the tool. Our ancestors didn't develop or use maps in order to enhance their capacity for conceptual thinking or to bring the world's hidden structures to light. Nor did they manufacture mechanical clocks to spur the adoption of a more scientific mode of thinking. These were by-products of the technologies. But what by-products! Ultimately, it's an invention's intellectual work ethic that has the most profound effect on us. "
