This document is a slideshow by Julian Bleecker on design, science, fact and fiction. It discusses using prototypes to design hypothetical future worlds and technologies. It also explores how science fiction can envision futures that science fact cannot yet achieve, and how stories and fictional depictions can influence people's ideas about emerging technologies more than real prototypes. Quotes discuss using fiction for low-cost experimentation of ideas and how the future is often oversold and under-imagined.
