Once you dig even a little bit into this, though... you get a quagmire of old and useless information. Outdated sites never go away. They just become a constant burden on the whole system. Information that's been refuted and invalidated years back is still alive and kicking because a domain exists and can be indexed, and there's no chance to ever update it, since the owner is long since dead.

The longer this lasts, the more and more noise to information you get. It's like having an incredible information web and then giving it dementia.
