“Many people who moved from graphic design into UX and UI felt that part of that repertoire would be left behind. Today, I see the opposite. As AI tools allow more people to create interfaces, principles of composition, visual hierarchy, typography, color, and perception become differentiators again. After years of training the eye, problems with alignment, spacing, proportion, and consistency simply stand out.”
