The chapters in this book have offered a diverse and compelling look at the forms, meanings and implications of ‘post-networked’ urbanism – an urbanism of infrastructure that no longer assumes, either ontologically or epistemologically, some kind of ‘material’ or ‘ideal’ convergence of socio-technical systems around a networked confi guration, model or paradigm. Working from in-depth empirical investigation across very different urban contexts, they have explored the shifting social signifi cation of infrastructure and the transformative changes it does and may well bring about. The collection makes a substantial contribution to current debates about the nature and repercussions of urban socio-technical change.
