“If sound is birth and silence death, the echo trailing into infinity can only be the experience of life, the source of narrative and a pattern for history.” Drawing on Louis Chude-Sokei’s metaphorical, political and technopoetic investigations, this volume experiments with how the echo of past ideas of life and form has brought forth the technologies and lifestyles that our contemporary world is based on. The essays, conversations and artist contributions by Lisa Baraitser, Louis Chude-Sokei, Luciana Parisi, Gary Thomlinson, Maya Indira Ganesh, Wesley Goatley, Sascha Pohflepp, Sophia Roosth and Xavier Le Roy delineate a variegated array of technologies, creating an image of their past and their future potentials.
