So I went to Google to interview some of the people who are working on its search engine. And what I heard floored me. “The Star Trek computer is not just a metaphor that we use to explain to others what we’re building,” Singhal told me. “It is the ideal that we’re aiming to build—the ideal version done realistically.” He added that the search team does refer to Star Trek internally when they’re discussing how to improve the search engine. “It comes up often,” Singhal said. “For instance, we might say, ‘Captain Kirk never pulled out a keyboard to ask a question.’ So in that way it becomes one of the design principles—we see that because the Star Trek computer actively relies on speech, if we want to do that we need to work to push the barrier of speech recognition and machine understanding.”

What does it mean that Google really is trying to build the Star Trek computer? I take it as a cue to stop thinking about Google as a “search engine.” That term conjures a staid image: a small box on a page in which you type keywords. A search engine has several key problems. First, most of the time it doesn’t give you an answer—it gives you links to an answer. Second, it doesn’t understand natural language; when you search, you’ve got to adopt the search engine’s curious, keyword-laden patois. Third, and perhaps most importantly, a search engine needs for you to ask it questions—it doesn’t pipe in with information when you need it, without your having to ask.

The Star Trek computer worked completely differently. It understood language and was conversational, it gave you answers instead of references to answers, and it anticipated your needs. “It was the perfect search engine,” Singhal said. “You could ask it a question and it would tell you exactly the right answer, one right answer—and sometimes it would tell you things you needed to know in advance, before you could ask it.”
