IN THIS ISSUE Fuller's original ultimatum: make the world work for everyone or get fucked. Dunne and Raby call it speculative design. Some proposals stayed on paper, some got built and failed, some succeeded in ways nobody expected. Archigram's plug-in cities that never plugged in. Drop City domes that mostly collapsed but proved collective living could work. Constant's New Babylon that somehow spawned shopping malls. The proposals were wild. Some executions sucked. But speculative design isn't about success, it's about permission to imagine different futures.
