Żuk reads Archigram’s apparently impractical projects as an intuitive research programme whose cultural effects exceeded its meagre built production. The group rejected architectural solemnity, historical ballast and rationalist decorum, using comics, gadgets, capsules and megastructures to release invention from immediate feasibility. This intuition was not the opposite of method; it operated through prolific variation, graphic experimentation and deliberate naivety. Plug-In City, Walking City and Instant City functioned as conceptual prototypes that later resurfaced in high-tech architecture, digital urbanism, capsule housing and the imagery of smart infrastructure. Żuk also identifies the historical reversal embedded in this success: Archigram’s extraordinary technocratic future has become ordinary, while optimism about continuous innovation has yielded to surveillance, ecological crisis and accelerated obsolescence. The essay bridges architectural historiography and technological criticism by asking how unrealised images acquire causal force. Its precise contribution is to show that speculative failure can become infrastructural success, though often in forms stripped of the emancipatory exuberance that first made them imaginable.
