This document provides an overview of design fiction and how it uses science fiction concepts to envision potential futures. It discusses how design fiction examines emerging technologies and positions them for integration into society through speculative design projects. One such project discussed is United Micro Kingdoms, which imagines future scenarios around self-driving cars, large communal bikes, a moving mountain train, and lab-grown "biocars". The document also briefly mentions Hugo Gernsback, considered the "father of modern science fiction", and his envisioning of technologies like TV glasses decades before they were realized.
