I'm working on a search product now. I find it really fascinating that many people immediately know and have adopted this "specific-type general-type" query structure, whereas many others have no idea.

It feels like we're on the verge of slowly evolving a new human-computer communication language. Definitely within the next 20 years it will happen. Not just a list of instructions or model descriptions like programming languages are, for example you can't translate an arbitrary Engish sentence into a programming language. No, I think this time we're watching a full language, in the linguistic sense, evolve in front of us.

Of course, search engines will also have to evolve beyond the "do-know-go" communication types that they're married to now, to get to the next stage.
