JAMES VINCENT, The Verge; The scary truth about AI copyright is nobody knows what will happen next

"...is any of this actually legal?

The question arises because of the way generative AI systems are trained. Like most machine learning software, they work by identifying and replicating patterns in data. But because these programs are used to generate code, text, music, and art, that data is itself created by humans, scraped from the web and copyright protected in one way or another.

For AI researchers in the far-flung misty past (aka the 2010s), this wasn’t much of an issue. At the time, state-of-the-art models were only capable of generating blurry, fingernail-sized black-and-white images of faces. This wasn’t an obvious threat to humans. But in the year 2022, when a lone amateur can use software like Stable Diffusion to copy an artist’s style in a matter of hours or when companies are selling AI-generated prints and social media filters that are explicit knock-offs of living designers, questions of legality and ethics have become much more pressing."
