Just want to make sure people understand what they are arguing, because I've seen this argument come up, and it is not fact-based. The AI tools most commonly used today were not trained exclusively on publicly available and/or purchased books, films, and games. It was trained on literally pirated works. Multiple major AI providers have admitted to this in court already.
And it is not as if modern AIs were trained on one or two pirated things, but potentially millions of them. We do not currently know exactly how many, because the furthest-along case (Anthropic) settled out-of-court for a billion-dollar settlement.
So just to be clear, the argument being made in the quote below - while an argument we could (and perhaps should) have in the future - is not one we need to have right now, because it is irrelevant to the current facts. We can confine ourselves today to arguing about literal piracy - the analogy is if artists usually learned to draw by going to the bookstore, stealing all the books there without paying for them, and bringing them home to keep.
Do you really not understand that all art mostly is and has been "pirated", as you want to call it? The ratio of new ideas vs existing ideas is very low, with and without AI. Baldur's Gate 3 for example, what did that game NOT steal from previous works?
