I disagree strongly.
Slop means “high volume, low effort garbage,” and it was a term even before LLM/diffusion proliferated.
“Anything AI generated is slop” was not the original definition, and it cannot be applied consistently. You’re probably on a computer filled with “slop” right now, if that’s your definition. You’re using it in nearly every website you visit regularly, you were touching it in media well before Stable Diffusion or ChatGPT were even out.
