I replaced Animal Crossing's dialogue with a live LLM by hacking GameCube memory

Presumably the author encountered it by accident and then thought it was an amusing contrast with the Animal Crossing setting.

Yes I get it the LLM is trained on current news. But it's in very poor taste for the author to post that screenshot.

It looks like the news feed data is external, not part of training, same as the character sheet data (at least according to the diagram). This makes sense from a design perspective as then you don't need to retrain the model each time the news changes.

When an unplanned result is worth qualifying as poor taste instead of humorous is a debate unlikely to be resolved on HN, but it doesn't need to be to explain why the author bothered to include it when documenting their experience.
