While I would like to believe you, doesn't this legal document linked by the article show that, in at least one of the cases, the author WAS trying to apply with himself, "Mr. Allen", as the author? And not the AI?
If SCOTUS is saying that AI works, even those co-authored by humans, are not eligible for copyright/patenting;
Doesn't that mean any code-base that uses AI generated code does not have an implicit copyright holder? And thus even the human constructor does not have the right to apply any license [closed/open] onto it whatsoever?
