How would it ever know the answer it found is true and correct though? It could as well just repeat some existing false answer that you didn't yet find on your own. That's not much better than hallucinating it, since you can't verify its truth without finding it independently anyway.

I would be ok with having an answer and an explanation of how it got the answer with a list of sources. And it does just that - the only problem is that both the answer and the explanation are fabrications after you double check the sources.
