According to Guns, Germs, and Steel, under what kinds of conditions does technology develop?
You can answer this question by reading in Chapter 13. Beginning on p. 260 in the paperback edition of the book, Diamond discusses this issue. He says that the major condition needed for technology is the existence of food production.
Food production allows people to live in one place. This lets them accumulate possessions that they cannot easily move from place to place. This would make it worthwhile to invent technology because it could now be kept in one place instead of having to try to carry it from place to place. In addition, food production allowed some people to specialize in the creation or use of technology. Farming created a surplus of food that allowed some people to do work that had nothing to do with getting food. Some of these people could work making or using technology.
Thus, the existence of agriculture or food production is the main condition needed for the development of technology.
