Are you also against tools like Google Translate, which were trained on large amounts of copyrighted text? 

I don't see why learning (machine or human) would be classified as stealing.

I'm not the most knowledgeable about how Google Translate was created so I'd have to know more about the process to be sure of my opinion.

But at face value. I don't perceive an AI learning grammatical or syntax rules the same as an AI "learning" art.

Language has rules. Art does not. The way an AI accomplishes these two things are different. 

In human terms It's like using books to learn how to speak or read. No one is copying paragraphs to later repackage and sell. They just learned the rules. And if they get a job as a translator whatever.

But in the case of art. No one is learning how to paint or draw. They're stealing multiple artworks from different people and splicing them together in different ways. Stolen art that's been repackaged to make a profit.
