Yeah, but this is a problem where I can think of plausible solutions without hand-waving radical AI advancements. For a factual claim, it could look at each sentence and see if the equivalent information exists on Wikipedia, or another online source, or even a book. And then link to that source. Google has already digested all that information, so it's just a matter of finding clever ways to connect them. I don't think it would ever be flawless, but it could be turned into an extremely capable research assistant.
