The message at the beginning of the twenty-first century was clear for Mark Wigley: “Nowhere escapes the net.” Most representatively, architecture, the paragon of certainty and permanence, was said to have dematerialized into and through a ubiquitous network logic: “the architecture of walls, doors, and locks gives way to that of passwords, firewalls, public key encryption, and security certificates... buildings dissolve into information flows.” “But”, Wigley prods, “what if we are actually at the end point of the network logic?” What if contemporary network architecture is not only an echo of the post-war discourse on networks, but “an echo of an echo”, that which “simply realizes nineteenth-century fantasies that were acted out throughout most of the last century?” Wigley’s assault on forgetting charges modern architecture with the twin offense of historical continuity and technological dilletantism, doubly conjuring an unmentioned Banham as he likewise reduces the work of Archigram and their contemporaries to “polemical images”. Indeed, Archigram provides the pivot wherein “the grid gives way to the web. Movement in the spaces defined between intersecting lines gives way to flow within lines”. Before we re-enter the echo chamber, then, we briefly pause at this transition to ask just what were these nineteenth century fantasies? How were they embodied in, prepared by, and played out through various manifestations of the grid?
