I'm somewhat curious about the legal status of publicly using / exhibiting and/or selling uncopyrightable media, such as AI generated imagery and video. If it is uncopyrightable, is it also a free for all - as in once publicly exhibited it is "free media" anyone can take and remix? What about AI generated media that includes / incorporates copyrighted elements, but used the legal loophole of parody? As parody, anyone can include copyright protected elements of others in their original works under US copyright law because satire is protected speech. If someone were to create a "satire AI" does that completely break copyright law?
