I agree with you. Maybe AI can generate designs that look moderately good and aesthetically pleasing for UIs that solve known problems in a prototypical way.[0] That is useful, especially for simple utilities, internal tools, or hobby projects. However, I have yet to see AI solve new design problems, improve on old problems, and create a unique design style that defines a brand and separates it from competition.
