Great take. A mixtape can be greater than the sum of its parts!

I believe that a lot of the judgement is also connected to the quality of the works. "Slop", while doubtlessly accurate for today, may be a rather weird description in a couple of year if the rate of progress continues to accelerate like it has.

Although I've already heard people starting to refer to DeviantArt and the like as full of "human slop" so perhaps this is just modern language that's evolving and completely unrelated to AI.
