I think it might go further than that, a whole lot of the commission and entry level illustration work is pitched as "draw this scene in a style similar to x" or "draw my character doing x thing in y style". AI has the potential to completely gut this area (and I suspect that the number of artists employed doing this type of work is substantially higher than the few pushing in novel directions).

This changes the design and availability of the software tools, the willingness for educational institutions to engage in these topics, and may even reduce the idea of a professional artist back to high art only (and we only need like 50 artists a year thanks).
