Ah, well if you want the Columbia Journalism Review has a good summary of the developments and links to various other opinions, particularly in the following paragraph:

According to a recent analysis by Alex Reisner in The Atlantic, the fair-use argument for AI generally rests on two claims: that generative-AI tools do not replicate the books they’ve been trained on but instead produce new works, and that those new works “do not hurt the commercial market for the originals.” Jason Schultz, the director of the Technology Law and Policy Clinic at New York University, told Reisner that there is a strong argument that OpenAI’s work meets both of these criteria. Elsewhere, Sy Damle, a former general counsel at the US Copyright Office, told a House subcommittee earlier this year that he believes the use of copyrighted work for AI training is categorically fair (though another former counsel from the same agency disagreed). And Mike Masnick of Techdirt has argued that the legality of the original material is irrelevant. If a musician were inspired to create new music after hearing pirated songs, Masnick asks, would that mean that the new songs infringe copyright?
