"Cheap-to-generate" mediocre content forces the floor expectation to rise, becoming the "minimum", which raises expectations of "current mediocre" further. Its largely invisible, slow process, where you can't gauge past "floor-level" expectation for content, because it implicitly assumed the 'current year' standard is the norm(while its evolution of expectations). In a few years, expectation for "mediocre slop" would likely include stuff that considered top-level today, but has some minor deficiencies and the "slop of years past" would be relegated to unusable/useless junk, like\ e.g. Stable Diffusion 1.5 images and GPT2 texts.
