The way I see it, many of the "good" uses of LLMs boil down to easily counterfeiting traditionally-trusted indicators of human expertise, time investment, or intelligence.

For example: "Hey LLM, generate a smart sounding cover letter for a job at AcmeCo as a sales representative, highlighting my diligent work ethic and ability to generate new sales."

When the counterfeiting becomes widespread, those writing indicators become debased as receivers start to realize how easy they are to fake.

I wouldn't be entirely surprised if some of those prose-heavy documents started to move (culturally) toward raw bullet points.

"Slop" is a good way to put it. AI seems really useful for creating a huge sludge of "filler" art and words on a particular topic. The quality may or may not be good, but it can produce endless quantity of this slop.

So, if you need to fake a blog by generating 10,000 posts on a topic that are each, say, 1,000 words long, AI is great. If you need to make a web forum that, at a surface level, looks active, AI can generate all the fake posts you need. If you have something you can say in one sentence, but need to make your text 10,000 words in order to appease an algorithm or "look credible" then AI slop is the way to pad it out.
