Modern creative work originated in mid-century advertising agencies, and UX inherited their entire operational model. This inherited structure, characterized by rituals like the pitch room and the "account man," now hinders UX teams in the age of AI. The author argues for a reset, acknowledging the past value of advertising giants like Ogilvy and Chiat but stressing their current obsolescence. UX has adopted the agency's focus on selling a dream and performing for clients rather than prioritizing tangible, measurable user outcomes. This "hype over practice" mentality leads to deliverables being valued over actual impact. The account model, with its client-centric gravity, has also been absorbed by UX, often making users secondary to stakeholders' demands. Agencies historically sold campaigns as handoffs, leaving the actual success or failure to others, a practice mirrored in UX's focus on producing artifacts rather than achieving results. The "auteur" culture, celebrating singular creative genius, has also been imported, devaluing collaborative systems and shared components. This star system prioritizes individual talent over the creation of durable, scalable design systems. The author contends that AI's capabilities render these outdated agency models increasingly ineffective. A shift towards collaboration, measurable outcomes, and user-centricity is crucial for UX's future success.
