Design did not become UI. It was reduced to UI by stakeholders who mistook the most visible layer for the whole discipline. The article traces this collapse from the fragmentation of HCI specialisms in the 2000s and 2010s, where UX mapped journeys, UI dressed wireframes, and the holistic practice that gave us the Apple Lisa 2 desktop metaphor in 1983 got buried under agile sprints and component libraries. The result: UX became a byproduct of business objectives, not the force shaping them.
Now AI is flipping the original paradigm. Machines were once limited, so humans adapted to them. Designers built metaphors, folders, desktops, buttons, to translate machine logic into human understanding. Today, machines can parse natural language, which should make those metaphors obsolete. But the chat interface is actually a regression: we moved from CLI to GUI in the 1990s, and now LLMs have dragged us back to text, dressed up in the metaphor of conversation to mask the complexity. The button is still a handle. We still need the handle to open the door.
The argument worth reading in full is not about whether designers survive automation. It is about what the discipline was supposed to be before it shrank. The author, citing Maximillian Piras on interface abstraction layers and Jakob Nielsen on autonomous agents, argues that AI strips away the commodity work and forces a return to design's core function: understanding what people need and enabling them to achieve it. The question left open is whether the next abstraction layer beyond conversation will finally let designers stop explaining the machine and start solving the human problem.
