Everyone is a designer. But while many practitioners may be looking for solutions or ideological certainties, Easterling argues that solutions are mistakes and ideologies are unreliable markers. Instead, Medium Design speaks to anyone looking for alternative approaches to the world's unresponsive or intractable dilemmas-from climate cataclysm to inequality to concentrations of authoritarian power. Such an approach joins many disciplines in considering not only separate objects, ideas and events but also the space between them.

In case studies dealing with everything from automation and migration to explosive urban growth and atmospheric changes, Medium Design looks not to new innovations but rather to sophisticated relationships between emergent and incumbent technologies. It does not try to eliminate problems but put them together into productive combinations. And it offers forms of activism for modulating power and temperament in organization of all kinds.
