> Yes but with AI, in principle, there is more wriggle room to present a spectrum of opinions on a single topic.

I mean, this sounds impartial but isn't. If you have an article on the planet Earth and present a spectrum of opinions on whether it's round or flat, you're not being balanced; you're implicitly supporting flat-Earthers and their trollish beliefs by taking them seriously.

This has countless parallels in political discourse. Trade flat-Earthers for (actual) neo-Nazis; it's probably not a "spectrum of opinions" you want to broadcast without passing any judgment. It's not the role of an encyclopedia to be a free speech platform.

I'm not really saying this to defend political articles on Wikipedia. It's just that I don't think you fix it by taking an LLM trained on Wikipedia, and telling it to regenerate the articles "without bias".
