Now, clearly, there aren’t yet enough Siri users to make even a thumbtack-sized dent in what’s left of Yahoo, never mind Google. But I’m not talking about this year or next year, but the world five or ten years from now.

If Siri succeeds, with Apple at the helm, it could potentially capture and redirect a material percentage of activities that currently run through search engines. Today we can get basic facts and restaurant recommendations, but I won’t be surprised if everything from ordering on Amazon to getting customized health information migrates to Siri. The smarter Siri gets, the more directly it provides information and services we need, and the wider range of tasks it performs for us.
