He says that using the set of questions and answers from one model to train another model (deatilation) is cheaper than training the model without those datasets.

But he didn't mention that training any model from a set of texts and books is much cheaper than writing those books in the first place.

In other words, it's ok when Anthropic learns from others, but it is not ok when others learn from Anthropic.

It's also cheaper to just pirate the author's work, which Anthropic has also done.
