Those numbers originated somewhere, for example a 3 from Europe and a 4 from Asia. A working computer thus requires more than functioning circuits. It also requires a far-flung institutional arrangement that provides for the standardized capture of data. Think next about the settings in which computers are used. It is extraordinarily common for organizations to invest large sums in complex computers without any investment in training.
Schools often invest their scarce resources in computers without any thought to the curriculum.
In some cases the responsible authorities are duped by claims that the systems are easy to use. In other cases it is assumed that computers will pay for themselves by displacing staff, and further investments in human capital seem like the opposite of that intention. Computers are easy to see, but webs are not. This effect is especially pronounced with the Internet. This made perfect sense in places like MIT and UCLA, where the researchers could depend on a web of skilled people and advanced technical resources.
