"Back in 2004, I asked [Google founders] Page and Brin what they saw as the future of Google search. 'It will be included in people's brains,' said Page. 'When you think about something and don't really know much about it, you will automatically get information.'
'That's true,' said Brin. 'Ultimately I view Google as a way to augment your brain with the knowledge of the world. Right now you go into your computer and type a phrase, but you can imagine that it could be easier in the future, that you can have just devices you talk into, or you can have computers that pay attention to what's going on around them and suggest useful information.'
