One could argue that whereas once it was necessary to verify the source, now it is necessary to verify not just the source but also the LLM derivation of it, (which may be subtly mangled) - and the source may no longer be readily apparent.
I think this is a good thing. In the past you would remind people, hey, after you find your wiki article, "please" go verify. But wiki was "good" enough most of the time, that people found verification to be often time redundant.
But now with LLMs everywhere, people will realize it is necessary to verify.
