The idea that AI is not inherently low effort is absurd. If using AI were more effort than not using AI, why would anybody use it?
I mean, I can kind of see a “conceptual artist” spending weeks on an AI stick figure that they could have drawn in less than a minute by hand to make some sort of nonsensical point about generative AI and human effort, but that’s not the kind of project we are seeing on itch.io.
You can claim that the defining characteristic of “slop” is low quality, not low effort, and that high quality can result from low effort. But you can’t deny that using generative AI is low effort.
