I think they have to; while at first glance AI generated content is impressive, it becomes noisy and sameish at larger scale or the more you read it. I'm of the opinion that AI is here to stay and a valuable tool for many use cases, but writing authoritative content ain't it. Wikipedia is fighting it (and other influences from before AI, like unsubstantiated claims and whatnot), I hope the scientific community and journalism steps up too.

I absolutely understand where you are coming from, and I agree to a point. If you're of an age where you actually read a printed encyclopedia, the tone and voice of the entire set was sameish as well. The difference is that it didn't sound LLMish like LLM text does. I know that printed encyclopedias would have been vetted by editors, and I feel this is the key difference. Editors not only knew grammar rules, but had that sense of good writing practices that's hard to write down as rules. A piece of text passed through a good editorial review will read human while LLM text reads as LLM text.
AI is great at making poor writing good. I've had good luck having AI turn my rough draft into something readable. (just check my comment history to see how bad my rough drafts normally are). AI is also reasonably good at research and fact checking. But in all cases you need to think before you accept anything AI says. AI generated content all too often hasn't been checked, some is good but some is awful and an expert needs to decide which is which.
That is AI is a tool. I've driven screws with a hammer - it worked in a pinch, but it was not good. People have also used hammers to kill others.
Wikipedia is also a training source and shouldn’t also be a model output for content. Eventually it will be an oroborus, but it seems prudent to avoid that for as long as possible.
