What will wireless media be like in the future? How might they change people and societies? Will the future differ significantly from the past? Wireless Futures argues that meaningful answers to these century-old questions depend equally on markets, technical limits, and sociotechnical imaginaries of media change. Before wireless came to mean 'Wi-Fi,' before 'the wireless' meant 'radio,' even before the first trials in radiotelegraphy, it was a central object of financial and theoretical speculation. Wireless Futures unpacks the speculative media question for the case of German modernity. Interrogating the materiality, temporality, and contingency of wireless, this critical project contributes to media philosophy, modernism & modernity studies, and German literary & cultural studies. Wireless Futures models an approach to speculative media based on testing out the limits of media knowledge and questioning the limits of limit-thinking. It shows how the present continuously remakes connections between the past.
