Makes sense, but it seems to me that the ability to launder disinformation is more a function of the trust people put in LLMs than any inherent property of their own. As some other comments indicate, this also was and is a problem with Wikipedia. It's possible trust in LLMs will follow the same trajectory as trust in Wikipedia, which seems to have been pretty non-linear (like, we rarely see "Do not cite Wikipedia" anymore.)

I think eventually things would settle on an approach similar to your example of the links: look at multiple sources and arrive at a balanced overview that includes the trust level and biases of each sources. I think the pieces are in place, just need to be put together. E.g. already AI overviews (especially on Amazon product reviews) are essentially of the form "Some say A but others say B" which has the benefit of a) clearly being second-hand information, and b) not sounding so authoritative, letting readers draw their own conclusions.
