In this piece, Cory Doctorow critiques the predictability of the future in science fiction and discusses the societal implications of predestination versus human agency. He argues that viewing the future as set in stone stifles innovation and change, advocating for a more activist approach to shaping our destiny. Doctorow condemns the notion of 'inevitabilism' and suggests that science fiction, rather than serving as a predictive tool, should inspire us to take charge of our society and make radical changes.
