Your answer reminded me of the Ford quote: "If I had asked people what they wanted, they would have said faster horses."

I don't mean that in a derogatory sense, I just strongly believe that in 20 years we'll look back at our Googling years and wonder how we managed to find anything at all. Who know what the next pattern of information retrieval will be, but I personally think it'll be an even bigger jump than the jump from reference desks and encyclopedias to Google.

Edit: okay, maybe not 20 years. Decades, perhaps.
