We have behemoth Goliaths that are living dinosaurs that engage in hierarchical domination of what are really illusions: text, symbols, images. All we need now are the behemoths to mint their own $, copyright it and the circle is complete. Yet these are merely simulations in search of a reality that AI can't deliver, and so the behemoths are using all techniques to remain relevant. It's stillnly one step ahead of a magic act. Obviously they are finished, ready for obliteration by insightful, imaginative succession. Bureaucracies are all targets for replacement, especially Doctorow's type of prose.
