Technology, thought of as the ensemble of utilities and devices and of their impact on our lives, proceeds in steps, each of which seems plausible. This kind of development also encourages the view that technology is value-neutral. It always can be used both for good and ill, and we decide how to use it. The production of food and the development of eating illustrate the trajectory of plausibility, but they also demonstrate that the view of technological neutrality is mistaken. People do not decide to become overweight or obese. The development of teaching also exhibits the semblance of plausibility and neutrality. Technological innovations are uncritically hailed as one more step toward better information delivery. But the example of eating should warn us that inducements are built into teaching technology that will produce analogs to overweight and obesity. (Contains 5 notes.)
