I think in a year LLMs are better at writing Wiki articles than the p90 quality Wikipedia page today.
They have access to _huge_ volumes of information—books, research papers, PhD dissertations, newsletters from experts, peer-reviewed articles. They're getting better every day at organizing it. Claude has a (beta) citations API, which forces the LLM to directly cite sources and use direct quotations.
They'll get better and better at managing translations—maybe not them translating, but them finding resources in other languages, using a translation tool, then pulling in that information.
Will they be perfect? No, but good lord is Wikipedia not either. Will they hallucinate, probably sometimes, but, again, the median Wikipedia author does not have a New Yorker fact checker at their side.
I think we overestimate how good humans are at this. And it's far easier to validate cited sources than it is to consume and craft the original writing.
