Any attempt to "eliminate" all bias would just introduce massive bias. The only solution is building a healthier democratic community.
A major reason people are obsessed with bias on wikipedia is because it is the only usable encyclopedia now. Back then even just in the US and published in english there were more than a dozen different encyclopedias competing with different scopes, intended audiences, viewpoints, arrangements, features, editorial policies, etc. And the publishers were more diverse and not monopolistic. There simply wasn't a need for any single one of them to be bias-free.
I feel that there is a trend in tech that is intentionally and sneakily creating a problem in order to sell the solution that we don't really need in the first place.
Another important reason why AI content would be more generic is that they would tend to err significantly on the safe (or shall we call it sterile) side as content moderation is completely done by AI. You won't be able to get any fair appellate treatment anymore. If an AI thinks your post has "problems", you can do nothing but swallow it.
Isn't this just a paraphrase of the core goals of liberal education? No offense, but I think this sentiment has already been elaborated fully by pioneers of the liberal education in the 20th century.
Also, the young wikipedia was very different from what it is today.
