The headline is downright wrong, and the entire body of the article based on anything factual fails to support the thesis that the headline and article keep trying to push: the US Copyright Office said no such thing. They said that an AI cannot hold copyright, not that AI generated artwork cannot be eligible for copyright. The article even directly quotes this from the Copyright Office:
> The Office “will not register works produced by a machine or mere mechanical process that operates randomly or automatically without any creative input or intervention from a human author.”
They key word there is any: if there is creative input from a human, then that doesn't apply. To me, this says they would treat an AI like any other tool an artist might use to create art: as a tool; but there must still be creative input, and the copyright is still awarded to a human being (or, as the plaintiff additionally tried to argue that the AI was a "work for hire", a company and there must be some employee, but still not an AI. The office found this argument unconvincing, see the next link.)
This seems to be the original ruling from the Copyright Office, from Feb of 2022: https://www.copyright.gov/rulings-filings/review-board/docs/...
This seems to be an appellate decision from Aug: https://cafc.uscourts.gov/opinions-orders/21-2347.OPINION.8-... (so I'm a bit curious what is happening now, but as TFA fails to cite it's sources …)
