I suspect in practice we're going to start seeing a kind of epistemic hardening analogous to the hardening of software supply chains that's been going on with reproducible builds and such over the last decade or so. A Wikipedia citation will be linked into a matrix of automatically validated claims.

It will no longer be enough to just write some text on a page and provide an arbitrary link. When you want to make an edit to an established Wikipedia page it will be checked against a dense web of LLM/embedding-backed autocitation pipelines that form a weave of logic your edit must fit into.
