Agreed. This is a fair take. But I am still very skeptical. :-) When being a DJ you are still in the center of the attention of your audience as a human. "What's laid next on the turn table?" And also very important, the DJ is putting music from real humans onto the turn table. So if you go down the ladder, you still consume art from humans. With AI music this is only the case for a very small extend, the training set, and no-one recognizes the real contributors to the training set.

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.
