NN/g: generative UI will make designers set constraints, not screens

Nielsen Norman Group's argument is that generative UI, interfaces assembled live by AI for one user rather than designed once for everyone, will push designers toward what it calls "outcome-oriented design": specifying goals and constraints for an AI to satisfy rather than laying out screens and components. Their flight-booking scenario shows Delta serving 190 million distinct personalized results instead of one shared design. The piece is candid about the costs: privacy demands from the context data needed, and a usability tax from interfaces that never look the same twice, undermining the learned familiarity static UIs provide. It reads as a genuine reframing of the designer's job, though the timeline and processing power required stay openly unresolved.
