"Slop" is a pretty effective dismissal at the moment, but I fully expect the term to get hijacked by marketing the same way "hallucination" did. Soon you'll hear CEOs boasting that their AI generated 62% less slop, or whatever.
It's all slop. The prettiest, most convincing genAI image in the world is still slop. A heart-breaking work of staggering genius produced by an LLM is still slop. Slop is slop not because it's poorly done, but because it's produced by a process that by definition cannot care about what it's creating.
