Earlier quoted context omitted.
Wikipedia is literally a spin-off of a porn company. From that point on, where it came from or who founded it is not so important. The question is how it acts today. It is a highly-political organization supporting lot of “progressive” ideas, California-style. So if you like reading politically biased media it may be for you. If you are seeking for a global view you better ask different LLMs for arguments and counter…
Yes LLMs that don't disclose sources are much better.
In everyday life, you cannot read 20 books about a topic about everything you are curious about, but you can ask 5 subject-experts (“the LLMs”) in 20 seconds
some of them who are going to check on some news websites (most are also biased)
Then you can ask for summaries of pros and cons, and make your own opinions.
Are they hallucinating ? Could be. Are they lying ? Could be. Have they been trained on what their masters said to say ? Could be.
But multiplying the amount of LLMs reduce the risk.
For example, if you ask DeepSeek, Gemini, Grok, Claude, GLM-4.7 or some models that have no guardrails, what they think about XXX, then perhaps there are interesting insights.
