I think that it's important to realize that "AI Art" of all kinds aren't working alone. None of them are, on anything large scale.

• A human requests a specific thing that they are interested in. They instigate the process.
• The AI churns out a ton of different results, some awful, some mediocre, some good, because they don't know the difference.
• A human sifts through all the results, picking through the good and the bad to find something that they personally thing is worth using.
• (optional) A human might tweak the final result to make it better and more interesting.

Many new tools have changed industries, like the printing press or electric drill or overhead crane, often changing the number of workers needed and how they are used. AI is the same, and it's probably not going away.

Complaining about AI is like complaining about digital art vs physical painting. Yes, photoshop changed a ton of things. Does that mean that photoshop should be banned? Or is it just a tool?

AI will change a lot of things. However, all progress does that. I don't think that AI will simply "replace authors". They'll simply change part of the process in some situations.
