I don't agree that users see them as databases. Sure there are those who expect LLMs to be infallible and punish the technology when it disappoints them, but it seems to me that the overwhelmingly majority quickly learn what AI's shortcomings are, and treat them instead like intelligent entities who will sometimes make mistakes.
They didn't claim to know it, they said "it seems to me". Presumably they're extrapolating from their experience, or their expectations of how an average user would behave.
