In previous eras there were many purists who considered photography not-art, sequencer and synthesizer made music not-music, other forms of (non-AI) digital art less legitimate than their more manual classical counterparts, etc. This is the same discourse all over again.
Is electronic music where the artist composes it on a screen and then hits 'play' music? I think it is, of course, but I have had experiences where I went to see a musician "live" and well... they brought the laptop with them. But I think it still counts. It was still fun.
AI slop is to AI art what point and shoot amateur photography is to artistic photography. The difference is how much artistic intent and actual work is present. AI art has yet to get people like Ansel Adams, but it will -- actual artists who use AI as a tool to make novel forms and styles of art.

Anti-photography discourse sounds exactly like anti-AI discourse to the point that you could search and replace terms and have the same rants.
Another thing I expect to see is novelists using AI to create at least passable live action versions of their stories. I don't think these will put real actors or actresses out of work for a long time, but I could see them serving as "sizzle reels" to sell a real production. If an author posts their AI-generated film of their novel and it gets popular, I could see a studio picking it up and making a real movie or TV show from it.
