This is the Stephen Thaler thing, which is pretty much just a nonsense digression from the real issues of AI art. For some reason Thaler is trying to assert that the copyright for an AI-generated piece of art should belong to the AI itself. This is a non-starter because an AI is not a person in a legal sense, and copyrights can only be held by legal persons. The result of this lawsuit is completely obvious and completely useless to the broader issues.
