AI and the Law Had a Rough Week: Sony, Disney, and the Maths Papers

Three stories this week showed that the legal system is catching up to generative AI, and none of them are tidy. Sony Music asked platforms to remove more than 260,000 tracks that imitate its artists — Harry Styles, Adele, Britney Spears among them. That's not a warning shot; it's a bulk action, and it tells every music-generation startup what 'responsible' is about to cost.

Disney sent cease-and-desist letters over AI-generated video that borrowed its characters, and ByteDance tightened safeguards on Seedance after similar threats. The pattern is consistent: the platforms that trained on everyone's IP are now the ones guarding their own, and the line around 'fair use' is being drawn in court rather than in a policy blog.

The strangest one was OpenAI's release of 722 AI-written mathematics papers on October 6. Some mathematicians called it historic; others called the volume a 'slopocalypse' and objected to the process. None of it has solved a Millennium Prize problem, but it forced a conversation about what counts as a proof when a machine writes the draft and a computer checks the lines.

For builders, the takeaway is unglamorous: the legal risk isn't abstract anymore, and it lands on the output, not just the training data. If your product generates a voice, a face, or a score, assume someone owns the thing it's imitating and act accordingly.

I'm not anti-progress here. I'm pro-not-getting-sued. The tools are incredible; the accountability framework around them is about two years behind. This week narrowed that gap a little, and mostly in ways that cost someone money.
