I think the point of differentiation is that being adept at Photoshop is a relatively advanced and specialized skill.
Manipulating an AI prompt to get what you want is also a specialized skill, but may require an order of magnitude or two less training, or obviate the need for the job entirely.
An art director for a campaign wants a set of images created, and a set of stock photos used. They may have a junior person on their team create those images, each of which could take hours to create, or they can produce those images with an AI tool, which might take minutes. Or the director may simply use the tool themselves for a few minutes and then hand it off to someone else to clean up "in post".
