AI generated content cannot be copyrighted because it is not the product of creativity, but the product of generative computing.
This article is about a lawsuit that sounds in unjust enrichment, not copyright. Unjust enrichment is an equitable claim, not a legal claim, and it’s based on a situation in which one party is enriched at the expense of another, unjustly. If an AI company is taking content without permission, using it to train its model, and then profiting off its model without having paid or secured any license from the original artists, that seems pretty unjust to me.
If you’re at all interested in how the law is going to shake out on this stuff, this is a case to follow.
