I'm going to go on a little rant here, so I apologize for that.
Copyright law is a modern invention (1710). It was designed to help allow authors to turn a profit. Essentially, with the printing press coming into existence, books were becoming cheaper to make, and so an author might pen a book, then someone would copy the book and sell it, making it hard for the author to make money.
Fast forward to today, and we have copyright on everything. Even nebulous concepts. Its absolutely ridiculous, and many countries don't respect copyright. Now, don't get me wrong, I think copyright in some degree is useful. I think direct copying, or minor changes to existing pieces rebranded is bad for everyone. In a world where mass production and reproduction is possible, some degree of direct copyright is the only way to incentivize creation of new ideas.
For example: The Harry Potter books in their entirety, in any language, should be under copyright protection. Any updates or basic grammatical changes should also fall under that copyright. In my opinion extended HP Universe (Same magic system, basic landmarks etc) should not fall under that copyright in my opinion, as long as the producer doesn't claim to be JK Rowling.
People should be able to make Micky Mouse fan fiction and sell it, in my opinion, as long as it doesn't directly involve existing portions of the copyright (it can't just be a few scenes inserted in an existing work).
Now, onto the actual crux of the AI discussion. AI artwork. Boy howdy does it make artists upset. I don't blame them, I heard recently that commission work is down something like 50%. The honest artists accept that this is part of life now, and argue rightfully that the quality and consistency of AI art doesn't beat an artist. I agree with them on that. If I'm producing a professional work, AI art won't cut it for repeated images of one character in different scenes (Don't get me wrong, AI art can actually do this, but it'll take you hundreds, if not thousands, of hours of work, so for the most part, just pay an artist. You'd have to generate about a hundred very high quality versions of your character that are all consistent, then go back and train a LoRA on that character, and you could maybe then generate consistent images to use throughout the novel.).
The other arguments against it are all flawed. Or at least all the ones I've seen are flawed. Here are a few.
"It was trained on my images without my consent!": Guess what? ALMOST ALL ARTISTS TRAINED ON OTHER ARTIST'S WORK WITHOUT THEIR CONCENT. If you, as an artist viewed other art, and to any degree liked some parts of it, you have now trained on another artists work without their express consent. That is how learning works. IF courts were to decide this was a problem from AI companies, I'd be willing to bet massive class action lawsuits would come up suing any artist that shares some degree of similarity with an older artist, because they also trained under the same rules.
"It'll make it impossible for artists to make money!": And? We didn't reopen coal mines, we shut down seamstresses, blacksmiths, the whaling industry, the horse and buggy industry, and countless others. We've settled this issue as society. We don't care if an industry disappears for convenience. However, if you look closely, all those industries do still exist, they're just much, much smaller.
"It sometimes produces almost exact duplicates of existing images!": First, everyone who argues this is disingenuous about it. They tried, very, VERY, hard to make it generate the near copy. Which, DUH, you can ask artists to do this too. Hell, we mass produce copies of images all the time. Either by just screenshotting a picture, or through an actual printer. We even have artists who specialize in making replicas of other artist's styles.
If anyone has others, feel free to throw them up so I can shoot them down, or maybe you'll change my mind. The genie is out of the bag, and I won't feel bad for using it when everyone else does.
