Subjective realities are on the ascendant. We are living through an era of unprecedented increase in our ability to craft our own realities through culture in powerful ways. It is now possible to create small-scale subcultures with the complexity and richness of large nation-states. With no more than simple text and meme-based messaging tools, we can create social spaces featuring symbols, grand narratives, and even private languages, at scales down to just dozens of humans. At Refactor Camp 2019, we will attempt to center the positive and generative side of the Great Weirding, while keeping a sharp eye on the Dark Side. We hope to bring together a diverse audience of reality builders and explorers to map out the emerging multiverse of subjective realities, and reclaim the positive potentialities of the human capacity for imaginative escapism.
