This guy's court cases are widely misunderstood by the general public.
In a nutshell: he's a crank who is trying to tell the court "I don't hold a copyright to the thing my AI produced, my AI holds the copyright."
And the court tells him: "Only people (or legal persons, like corporations) can hold a copyright. Your AI cannot. If you say that you yourself don't either, we can't force you to have a copyright on it. So I guess that thing has no copyright and is therefore in the public domain."
And then everyone gasps and exclaims "the court just ruled that AI-generated things are in the public domain!"
