The difference here is that the slop paradigm is not a set of intentionally designed UX choices that work well for users, it's a set of accidental commonplace LLM tendencies, not designed for humans, replicated ad infinitum that are making user experiences worse in 99% of cases. The use of white space is horrendous, the font choices are illegible, the color palettes lack sufficient contrast.

Yeah it's problem of sensibility. Like people do not realize that developing a sensibility and good taste here is an actual still that takes time, and is highly undervalued in tech circles with the exception of a handle of truly design driven companies.
