"There is a dark underbelly to the diversity of content and services that the internet has brought us, ... "
... one that leaves it more vulnerable to centralization, not less. The Internet with its uniquely open design has led to a moment when all other information networks have converged upon it as the one "superhighway," to use the 1990s term. While there were once distinct channels of telephony, television, radio, and film, all information forms are now destined to make their way increasingly along the master network that can support virtually any kind of data traffic. This tendency, once called "convergence," was universally thought a good thing, but its dangers have now revealed themselves as well. With every sort of political, social, cultural, and economic transaction having to one degree or another now gone digital, this proposes an awesome dependence on a single network, and a no less vital need to preserve its openness from imperial designs."
