Context: You see how increasingly the only way we in the advanced industrial nations, with our bewildering technology network, can survive, is by selling bewilderment and dependence on technology to the rest of the world. Or is it not bewilderment and dependence, but a healthier wealthier better way of living than the old way? And, yet, whether or not you dress up technology to look local, the technology network is the same. And as it spreads, will it spread the ability to use machines, as we do, without understanding them?
