Is it though? What if I were to look at your art style and replicate that style manually in my own works? I see no difference whether it's done by a machine, or done by hand. The reality is that every art is a derivative of some other art. Interestingly, the music industry has been doing this for years. Ever since samplers became a thing, musicians spliced and diced loops into their own tracks for donkeys years, and created an explosion of new genres and sound. Hip-hop, techno, dark ambient, EDM, ..., all fall into the same category. Machine learning is just another new tool to create something.
Personally, I'm all for AI training and using human artwork. I think telling it not to prevents progress/innovation, and that innovation is going to happen somewhere.
If it happens somewhere, humans who live in that somewhere will just use those tools to launder the AI-generated artwork, and companies will hire those offshore humans and reap the benefits, all the while, the effect on local artists' wages is even more negative because now they don't have access to the tools to compete in this ar(tificial intelligence)ms race.
Most people do not understand the purpose of copyright. Copyright is a bargain between society and the creator. The creator receives limited protection of the work for a limited time. Why is this the deal?
The purpose of copyright is to advance the progress of science and the useful arts. It is to benefit humanity as a whole.
AI takes nothing more than an idea. It does not take a “creative expression fixed in a tangible media”.
