## Nauti's Take

The 'memorization' argument is legally clever because it shifts the focus from the training process to the output – and that is where infringement can actually be demonstrated concretely. Britannica apparently did its homework, systematically prompting GPT-4 with queries about its own content. If the court agrees, 'how similar is the output to the original?' becomes the central compliance question for every AI provider. Retrieval Augmented Generation suddenly looks less like a technical choice and more like a legal necessity.
