Here's one way to think about it. Did you see Jeopardy when IBM's "Watson" super computer competed with all the earlier human champions? Watson was using a knowledge base and making some very diverse and obscure connections - sometimes with absurd results, but often with uncanny accuracy and speed.
If Google can mature their Knowledge Base technology in that direction, then they can have that kind of capability and apply it to all kinds of diverse search queries. Or so goes the hope.
