I think it depends on how we define what a 'search' is exactly. When you wear a future Google Glass and it's discovering that you're drinking an iced coffee instead of a regular coffee, did it do that by searching? If so, did it do 100 'searches' to discover this fact, where a search is a really an image search of static frames from your vision?

Or is a 'search' something that a person dictates to a computer to answer a question?
