I also think that the use is usually not plagiarism. After all, a generated image is not created by itself, but based on a human's idea. It is even the case that if someone else uses an AI image generated by you, this would not in principle be an infringement of copyright, because this is only reserved for humans. And AI is not human.

There were posts in which AI images bothered me because I felt that too many images were used, an overdose of AI, so to speak. And there are posts that are enhanced by an AI image.

I noticed one point recently:

I had combined an image from 4 AI images and 1 free image, which took more than 2 hours in total. But unlike some of my other pictures, there was zero response. This is also new, because such an effort is no longer seen or recognised today.

So, I think we are in the process of learning how to use them and how to dose them ;-)
