alt Hacker News> I'd like to understand why I can't use a song in one of my videos without permission/payment, but an AI company can train models using that song without having either.
Because training isn't redistribution.
You can also listen to the song and make a new one that sounds similar, just like the AI can.
To do that training, you must first obtain the item with the content you require. Did OpenAI purchase a copy of every book they trained their models on?
Answer: They did not. That is literally why there are dozens of ongoing lawsuits in progress.
