As a frame of reference, the act of reading is a human invention that’s only a few thousand years old. In Europe and the United States, mass literacy—meaning more than 50 percent of the population knows how to read—has only been around for about 150 years. In other areas of the world, such as most of Asia, the Middle East, and Africa, it’s much more recent.
