I'm guessing that most commenters here didn't read the article, and the headline itself was abridged by omitting the word "quite" in "quite like". The article isn't saying that nothing vaguely shaped like Wikipedia will never be created again. It's saying that there will probably be no room for a similar human-written encyclopedia in the future because the internet is changing shape and is morphing into something not conductive to having such a site.

"AI’s absorption of Wikipedia means that more people than ever are reading its content. Yet it also means that fewer people are visiting the site itself. When a Wikipedia link is suggested by a search engine, nearly a tenth of users click through. When Wikipedia is cited by an LLM, the clickthrough rate is only 0.33% (and not all credit their sources)."

Some folks saying are saying that AI will only accelerate the creation of future Wikipedias, and that's obviously missing the point. Yes, there might be Grokipedia-style entities, and some of them might not suck, but that's not the point.
