The end of the end, the beginning of the end: architecture, artificial intelligence and the exhaustion of the post-classical

Purpose This article examines how artificial intelligence (AI) is reconstituting the figure of the architect – not as an external disruption but as the latest instance of a recurring pattern in which mediating tools rewrite the discipline from within. Situating the present moment as the third in a sequence of paradigmatic “ends” diagnosed by Tafuri (1969/1973) and Eisenman (1984), the article traces a genealogy of the architect from Vitruvius through Alberti to the modern professional, and argues that generative AI has mechanically realized the post-classical project Eisenman announced as avant-garde provocation, thereby exhausting its critical force and demanding a fundamental redefinition of architectural labor. Design/methodology/approach The article employs a critical-theoretical methodology combining historical genealogy with contemporary empirical evidence. It constructs a genealogy of the architect-figure organized around successive mediating instruments (orthographic projection, notation, legal seal, computation, AI), drawing on Tafuri’s ideology critique, Eisenman’s post-classical theory and Carpo’s digital-turn thesis. This theoretical framework is grounded in recent empirical data, including RIBA’s 2024–2025 AI adoption surveys, Schneider et al.’s experimental study of client-AI co-design, Bernstein’s practice-based research and World Economic Forum labor projections. Findings The article finds that generative AI has industrialized the formal operations Eisenman theorized as avant-garde in 1984 – architecture without origin, without telos, without representational meaning – rendering the post-classical paradigm the default rather than the transgression. This exhaustion produces an asymmetric absorption: AI enters practice fastest where authorial labor concentrates (ideation, visualization) and is resisted where liability concentrates (documentation, certification), splitting the legal author from the substantive author. Five emergent functions of the architect are identified – dataset curator, question framer, output evaluator, liability bearer and system critic – collectively relocating architectural authority from form-giving to judgment. Originality/value The article offers the first sustained reading of architectural AI through the combined lens of Tafuri’s ideology critique and Eisenman’s post-classical theory, demonstrating that the diffusion model mechanically performs the very operations Eisenman demanded as deliberate aesthetic transgression. This reframing moves the discourse beyond the prevailing optimism/dystopia binary toward a structural analysis of how tools historically constitute the architect-figure rather than merely assist it. By identifying five emergent functions that relocate architectural authority from authorship to judgment, the article provides a theoretically grounded framework for rethinking professional identity and disciplinary self-understanding in the age of AI.
