Matter compilers receive their raw materials from the Feed, a system analogous to the electrical grid of modern society. The Feed carries streams of both energy and basic molecules, which are rapidly assembled into usable goods by matter compilers. The Source, where the Feed's stream of matter originates, is controlled by the Victorian phyle (though smaller, independent Feeds are possible). The hierarchic nature of the Feed and an alternative, anarchic developing technology, known as the Seed, mirror the cultural conflict between East and West that is depicted in the book. This conflict has an economic element as well, with the Feed representing a centrally-controlled distribution mechanism, while the Seed represents a more flexible, open-ended, decentralized method of creation and organization.
