Here is the problem: we are living with the unexpected consequences of low-cost information dissemination, or �cheap speech.� Cheapness is generally good, but it also creates strange consequences. Cheap corn, for example, makes us fat. Cheap drugs, like crack cocaine, can destroy neighborhoods. And cheap information is making us stupid.
As a society, the only answer is likely to be painful: an information diet. Consider the food analogy: in another age, food was scarce, and so everyone ate anything they could get their hands on. Today that approach will make you look like Andre the Giant. We have learned, albeit imperfectly, to eat more carefully. We similarly need to learn to regulate our information intake, or we�ll end up with brains that look like CNN Crossfire.
