At least Wikipedia is supposed to cite its sources, while AIs don’t.
Have you used one recently? The big providers all cite sources if give a research prompt.
Do you people even use the models or do you just lie about them?

AIs that were trained on data obtained through naughty channels actively avoid citing sources and full passages of reference text, otherwise they'd give the game away. This seems to increase the chance of them entirely hallucinating sources too.
