Opinions on generative AI aside, I'm pretty sure the legal consensus on the copyright surrounding it means whatever was generated is basically in the public domain, unless they've edited it in a way that's transformative.
You are wrong about this, there are literally right now huge arguments going on and legal battles likely to start soon over the fact that 'AI' generated content is effectively a giant plagiarism/synthesis machine, as the models are nearly always trained on /massive/ swaths of content that include /many/ copyrighted works, as well as stuff that was simply never given express permission to be used in such a way.
Valve, for example, has officially taken a side, a few days ago stating in a policy update that you are not allowed to publish a game with 'AI' gen art, dialogue, or code, unless you can prove the training set for the 'AI' did not contain any source material you do not have the rights to use in a for profit manner.
That's not what Valve's policy said at all. It basically says you have to promise you aren't infringing and disclose how it's used so customers can make their own decisions.
I didn't say I was certain - just pretty sure :P That was based on what was known last year, dunno if news on that have been updated yet. I'm bound to see it on Lemmy when it does. Thank for letting me know though.
