Strongly disagree. At least on English Wikipedia, articles tend to be high quality, and it's AI - not Wikipedia - that has repetition and redundancy.

AI isn’t one thing. The consumer AI bots (e.g. ChatGPT) are heavily dumbed down. Asking it a Wikipedia topic without prompting will of course produce low quality content.

With a good model , fine tuning & supervision AI can produce stellar content.

AI is at least a thousand tools. It’s a mistake to write it off so trivially.
