Depends. I'm sure that Google trained us to rephrase at least some of our questions as keywords and to not ask some complex questions at all- or at least to expect them to fail. Plus, in general we expect Google to mostly find the information that is already there, while there is a world of information that has not been made explicit by anyone. For example, "how many pizzerias are in this town" and "which one has the highest ratings by Italian customers" are two questions that I would never dream to ask Google. Yet they're possible and not too absurd to ask to an omniscient intelligence.
