AI companies are hoping for a ruling that says content generated from a model trained on content is not a derivative work. So far, the Sarah Silverman lawsuit seems to be going that way, at least; the claimants were set back because they've been asked to prove the connection between AI output and their specific inputs.
If this does become jurisprudence or law in one or more countries, licenses don't mean jack. You can put the AGPL on your stuff and AI could suck it up into their model and use it for whatever they want, and you couldn't do anything about it.
The AI training sets for all common models contains copyright works like entire books, movies, and websites. Don't forget that most websites don't even have a license, and that that unlicensed work is as illegal to replicate as any book or movie normally would be, including internet comments. If AI data sets need to comply with copyright, all current AI will need to be retrained (except maybe for that image AI by that stock photo company, which is exclusively trained on licensed work).
