I think "interactive clipart" is a great description. You are, I believe, totally correct that (at least for now) GenAI can't do what professionals can do, but it can do better than many / most non-professionals. I can't do art to save my life, and I don't have the money to pay pros to make the mundane, boring everyday things that I need (like simple, uncluttered pictures for vocabulary cards). GenAI solves that problem for me.

Similarly, teachers used to try to rewrite complex texts for students at lower reading levels (such as English Learners). That took time and some expertise. Now, GenAI does it prolly many tens of thousands of times a day for teachers all over the USA.

I think, at least for the moment, that middle / lower level is where GenAI is currently most helpful - exactly the places that, in earlier times, were happy with clipart.
