alt Hacker NewsCopyright has a lot to do with what we as a society want to protect and encourage. We want to protect an author that put the hours into creating a book, as opposed to the person creating a copy of that work. The person copying can claim they put in work too but the claim is not strong enough to override our preference to protect original authors.
Part of the problem with generated works is that it is lower effort like the person copying something. It’s not an activity that demands special protection like original authorship. I believe this is a large part of the reasoning.
AI is a monster to our current copyright system - monster in the philosophical sense, that is, an example that destroys the concept.
First, its creation is (claimed to be) extremely useful for society, but in order to be created it requires ignoring copyright for pretty much everything ever written. Something we kinda shrugged under the table.
Then, it introduces an extreme jump down in creation effort - so if the focus is protection of effortful creation, nothing with AI use qualifies. But of course, you'd want society to benefit from effortlessness in general, spending more effort than needed in a task is the opposite of efficiency.
