Making connections: A peek inside one of Google’s eight data centers worldwide, this one in Douglas County, Georgia. | AP

Thinking about Google over the last week, I have fallen into the typically procrastinatory habit of every so often typing the words “what is” or “what” or “wha” into the Google search box at the top right of my computer screen. Those prompts are all the omnipotent engine needs to inform me of the current instant top 10 of the virtual world’s most urgent desires. At the time of typing, this list reads, in descending order:

What is the fiscal cliff


What is my ip

What is obamacare

What is love

What is gluten

What is instagram

What does yolo mean

What is the illuminati

What is a good credit score

What is lupus

It is a list that indicates anxieties, not least the ways in which we are restlessly fixated with our money, our bodies and our technology — and paranoid and confused in just about equal measure. A Prince Charles-like desire for the definition of love, in my repetitive experience of the last few days, always seems to come in at No. 4 on this list of priorities, though the preoccupations above it and below it tend to shift slightly with the news.

The list also supports another truism: that we — the billion components of the collective questioning mind — have got used to asking Google pretty much anything and expecting it to point us to some kind of satisfactory answer. It’s long since become the place most of us go for knowledge, possibly even, desperately, for wisdom. And it is already almost inconceivable to imagine how we might have gone about finding the answer to some of these questions only 15 years ago without it — a visit to the library? To a doctor? To Citizens Advice? To a shrink?

That was the time, in the prehistory of about 1995, when our ideas of “search” still carried the sense of the word’s Latin roots — a search was a kind of “arduous quest” that invariably involved “wandering” and “seeking” and “traversing.” Not any longer. For those who are growing up to search in this millennium, it implies nothing more taxing than typing two words into a box — or, increasingly, mumbling them into a phone — and waiting less than an instant for a comprehensive answer, generally involving texts and images and films and books and maps. Search’s sense of questing purpose has already gone the way of other pre-Google concepts, such as “getting lost.”

That rate of change — of how we gather information, how we make connections and think — has been so rapid that it invites a further urgent Google question. Where will search go next? One answer to that question was provided by the billionaire double act of Sergey Brin and Larry Page, Google’s founders, in 2004, when pressed about their vision of the future by the former Newsweek journalist Steven Levy.

“Search will be included in people’s brains,” said Page of their ambition. “When you think about something and don’t really know much about it, you will automatically get information.”

“That’s true,” Brin concurred. “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 …”

Page, generally the wilder thinker, was adamant, though. “Eventually, you’ll have the implant, where if you think about a fact, it will just tell you the answer.”

Nine years on, Brin’s vision at least is already reality. In the past couple of years, a great advance in voice-recognition technology has allowed you to talk to search apps — notably on iPhone’s Siri as well as Google’s Jelly Bean — while Google Now, awarded 2012 innovation of the year, will tell you what you want to know — traffic conditions, your team’s football scores, the weather — before you ask it, based on your location and search history. Page’s brain implants remain some way further off, though both Google founders have lately been wearing “Google Glass” prototypes, headbands that project a permanent screen on the edge of your field of vision, with apps — cameras, search, whatever — answerable to voice-activated command. Searching is ever more intimately related to thinking.

In this sense, the man who is, these days, in charge of the vast majority of the world’s questing and wandering and seeking and traversing is called Amit Singhal. Aged 44, head of Google Search, he is a boyishly enthusiastic presence, who inhabits a much-mythologized office in Mountain View, California, somewhat in the way that the Wizard of Oz lived at one end of the Yellow Brick Road. Singhal is the man who pulls the levers that might just help you find a heart, or a brain, or the way back to Kansas. For a dozen years, he has taken over responsibility from Brin for writing and refining the closely guarded algorithm — more than 200 separate coded equations — that powers Google’s endless trawl for answers through pretty much all of history’s recorded knowledge. So far, he has never stopped finding ways to make it ever smarter and quicker.

To find Singhal, I go through all those by now second-nature travel preparations. I Google a hotel to stay at nearby in Palo Alto, view the options, have a virtual look around a couple before booking. I Google my flight times and check in. I Google a car hire firm, find the cheapest on a comparison site, and choose a car, and hook up to Google maps to plan the route of the 400 or so miles I’ll drive from Los Angeles northward. I Google information about where to park at the Googleplex, and Google the Street View of the walk I will make from the car to the right office building, past the replica T. rex outside. I Google a few interviews Singhal has given in the past. And then a day or two later I do it all for real.

There is something slightly disconcerting about the Mountain View Googleplex itself, which I guess has a lot to do with finding yourself in the physical space of so virtual an entity. At the end of last year, Google published photographs of its vast and ever-growing data centres for the first time. The images of our cloud of knowing were either inspiring or terrifying, depending on your point of view. Endless banks of servers, linked with primary colored Google wiring, stretched as far as the eye could imagine, a great outsourced brain thrumming in high-security hangars in Oklahoma, Ohio and Georgia, fed by all the world’s anxiety and curiosity. The control center of that unprecedented storage centre could hardly be more open access, however.

You can wander around the sprawling landscaped Googleplex campus or hop on a primary colored Google bike to cycle between buildings and nobody bothers you at all. The Googleplex was conceived by Brin and Page to encourage geeks to be sociable. It seems to work; it is overpopulated by a chatting and mingling crowd of what seem like quite intense postgrad students who look happy and healthy and are, though you would never quite guess it, often jaw-droppingly rich. The site is full of free cafes, punctuated by volleyball courts; every workspace has pool and table tennis tables; you can visit a doctor or a dentist, get a haircut, get your dry cleaning done, have a massage (Google’s masseuse became a stock millionaire), go to the gym.

It has book talks, movies and music events — when I visit English footballer David Beckham had just been on site as a “guest speaker.” There are whiteboard walls everywhere full of algebra and in-jokes; there is a learning space with classes in everything from mindfulness to Greek myth. And of course lots of gadgets. In the foyer is a mini wraparound Imax of screens that allows you to key in a postcode and stand in any street in the world. Fittingly, having Googled the way here, now I have arrived I find myself standing outside my house in London again, exactly where I was two days and a trans-Atlantic flight earlier.

Singhal, Google’s Mr. Search, has likewise come a long way to get here. He started out in a village in Uttar Pradesh in India, in a home that for the first eight years of his life possessed no screen at all. When one arrived in 1977, a black-and-white television, it carried for Singhal, he tells me, all the magic of prophecy. “There were two kinds of programs,” he recalls. “Programming for local farmers and reruns of American series such as Star Trek.” You don’t really have to think too hard to imagine which of these programs Singhal chose.

“I watched way too much Star Trek, to the extent that I could remember episodes by heart,” he recalls with a laugh, “and I deeply believe now that shaped my thinking. The fascination with flying through galaxies and talking to a computer that could answer any question was always there for me. But of course, I never imagined those problems would begin to be solved in my lifetime at all.”

Singhal found himself in any case in the right place at the right time. He started studying the idea of search as a graduate in America in 1991, the year the world wide web began making its connections. He did a Ph.D. and then ended up in the Bell laboratories at AT&T. It was only when he came to Google in the millennium year, however, that he experienced “a strange kind of discontinuity.” Everything that had seemed like science fiction all his life was suddenly within his compass.

To prove that point, Singhal takes his Android smartphone out of his pocket and, like Captain Kirk, talks into it. “Google: what is the population of London?” he says. “The population of London was 8.174 million in 2011,” the carefully conversational voice replies. “How tall is Justin Bieber?” he wonders. “Justin Bieber is 5 ft 7 in tall.” Singhal looks at me with childlike glee. “If I had gone to sleep 20 years ago and you had woken me up today and I heard that, I would be thinking, yes! And where do I sign up to fly to another galaxy?”

What he is demonstrating, however, he insists, is still just the beginning. Google search is, he says, with evangelical zeal, on the threshold of another epochal change in its fast-forward evolution. Having searched for a decade or so using the original brilliant principle of hierarchies of web-based links, the great primary colored knowledge domination machine has, Singhal suggests, “begun to learn how to understand the real world of people, places and things.”

To answer his question about Justin Bieber, Google already has to know quite a lot. It has to know Justin Bieber is a person and that tallness means height. “So you have already got to get to the semantics of what is being asked. But even that is not enough. Because beyond that there is this huge mass of unstructured text that we know as the web. And you cannot properly understand what was asked for without really understanding how you are going to go about answering it.”

Until now, Google has been an unprecedented signposter of knowledge. It has not “known” the answer to anything itself but it has had an awfully clever way of directing you to exactly the place you can find out. In some senses, that attribute is in the process of changing. This year, Google will roll out what it calls its Knowledge Graph, the closest any system has yet come to creating what Tim Berners-Lee, originator of the web itself, called “the semantic web,” the version that had understanding as well as data, that could itself provide answers, not links to answers.

The Knowledge Graph is a database of the 500 million most searched for people, places and things in the Google world. For each one of these things, it has established a deep associative context that makes it more than a string of words or a piece of data. Thus, when you type “10 Downing Street” into Google with Knowledge Graph, it responds to that phrase not as any old address but much in the way you or I might respond — with a string of real-world associations, prioritized in order of most frequently asked questions.

Five years ago, when John Battelle wrote his book “The Search,” which is still the definitive history of the subject, he concluded by imagining a future directly out of Isaac Asimov’s science fiction. “All collected data had come to a final end. Nothing was left to be collected. But all collected data had yet to be completely correlated and put together in all possible relationships. A timeless interval was spent doing that.”

Knowledge Graph, you might say, is the beginning of that “timeless interval.” Google has already come closer than anyone could ever have imagined to the “nothing was left to be collected” part of that equation. It is in searchable possession not only of the trillions of pages of the World Wide Web, but it is well on the way to photographing all the world’s streets, of scanning all the world’s books, of collecting every video uploaded to the public Internet, mostly on its own YouTube. In recent years, it has been assiduously accumulating as much human voice recording as possible, in all the languages and dialects under the sun, in order to power its translation and voice recognition projects. It is doing the same for face recognition in films and photographs. Not to mention the barely used possibilities of the great mass of information Google possesses regarding the interests and communications and movements and search history of just about everyone with a phone or an Internet connection.

This data has been collected not just for the purpose of feeding it back to us as accurately as possible, but also for the wider purpose: of teaching Google how to think for itself. Singhal has worked with what he calls “signals of salience” for the past dozen years, finding ever more accurate text- and link-based methods of making searches happen. But also, crucially, as these signals have become ever more sophisticated, Singhal and his team have been able to “observe the whole world interacting with the data, and with that we were able to begin to do something else, which was to begin to make the computer understand the context of what was being asked.”

The way in which this is done is quite simple. Search analysis is divided into “long clicks” and “short clicks.” A long click represents a satisfied customer. A user performs a search, clicks through on a result and remains on that site for a long time. They don’t come back to the result set immediately to click on another result or to refine their query. A short click is the opposite of a long click. It occurs when a user performs a search, clicks through on a result and quickly comes back to the result set to click on an alternative result. It represents a minor failure. We may think we are learning all the time from Google, but by virtue of this ongoing trillion-click analysis, it is learning far more from us.

In this way, as far back as 2002, Singhal introduced a refinement based on Ludwig Wittgenstein’s theory on how the meaning of words is always influenced by context. Searches for ambiguous terms began to look beyond the search terms for other related words. So a phrase such as “hot dog” would be understood in relation to mustard and baseball games, not overheated canines. “Nuance,” he says now, “is what makes us human.”

I imagine, I say, that along the way he has been assisted in this work by the human component. Presumably we have got more precise in our search terms the more we have used Google?

He sighs, somewhat wearily. “Actually,” he says, “it works the other way. The more accurate the machine gets, the lazier the questions become. So actually our lives get harder.” He had to work especially hard to correct and understand spelling errors and analyze synonyms. And all along the dream has been the old Star Trek one of providing the right answer to what you think you want to know even if you don’t know quite how to phrase the question. To work like a mind works, in other words. “The end game of this is we want to make it as natural as possible a thought process,” he says. “We are maniacally focusing on the user to reduce every possible friction point between them, their thoughts and the information they want to find.” Getting ever closer to Page’s brain implants, in effect.

Knowledge Graph is the first real demonstration of that prowess. It started a couple of years ago when, Singhal says, “We ran into this tiny company called Metaweb, which had, through a symphony of machines and humans, begun to perfect a system to present real-world people, places and things in a computer memory. The method seemed scalable. So we bought this company.”

By that point, Metaweb had stored 12 million reference points. Over the last two years, in its characteristic style, Google has quickly accelerated that to “over 570 million references with 18 billion factual connections between them.” (This is a sizable number: by point of comparison, the English version of Wikipedia has about 4 million pages.) Google is in the process of launching Knowledge Graph in seven languages and aiming to exhibit the same local intelligence in each.

Knowledge Graph’s project manager is Emily Moxley. She talks me though some of this intelligence. It goes quite a long way beyond being able to distinguish between an English query for football scores and an American one. “In Japan for example,” she says, “our analysis shows that people want to know quite a lot about the blood type of film stars,” so that will be a prioritized part of the instant Knowledge Graph in that part of the world.

Likewise, Japanese Googlers seemed short-click frustrated that the search for sumo wrestling data was not as accurate as it might be. “We worked on rectifying that,” Moxley says. “We thought at the very least we should be able to answer a certain depth of queries.” What kind of depth? “Somewhere at least in the most popular tens of millions,” she suggests.

More than that, Singhal wants to be sure all aspects of the data are properly in harmony with your desires. “If you wanted to find out about Dr. Martin Luther King’s ‘I have a dream speech,’ ” he says, “you might want the text, you might want a picture of him, but we guess that what you really want is a video clip of him delivering the speech — so how to get that to the top of your search.” Again Knowledge Graph can deliver that; it starts to know what you want to know.

In talking to Singhal, it is quite easy to get caught up in the Utopian possibilities of the technology and quite easy, of course, to forget that Google has also created wealth faster and more efficiently than any company in history; that it is probably the most effective generator of advertising dollars ever invented; and that a great deal of what it knows about us we might well want it not to.

All the Google employees I speak to adopt the same kind of reflexive flinch if you hint at any of this, if you suggest that their motives for all this data gathering, this knowledge sharing, might be anything other than pure. It is the same kind of “Why wouldn’t you trust us?” flinch that has powered the company’s growth through loyalty and that sees it refuse to reveal its own intimate search history even when threatened, as it is currently by the European Union, to prove that it does not artificially weight algorithmic results in favor of its own products and commercial partners.

Singhal rejects all of this. He winces when I ask: “What’s in it for Google?”

“We are a search people,” he says. “The thing that motivates me is to build a search engine that will outdo all my previous creations. Simple as that.”

Further, he believes, as a statement of faith, “that all information is empowering.” One of his favorite examples comes from his own family. Every year, Singhal returns to Uttar Pradesh and sees the transformations that the mobile availability of all the world’s knowledge has brought. And most years his father comes over to California. “My dad is a retired civil servant,” Singhal says, “and when he visited us he used to worry the whole time about returning home and taking presents through customs where the rules about what you could bring home were very complicated, and changing all the time, and he would get harassed and asked a hundred questions.

“I remember 10 years ago when he was here I showed him how to Google ‘Indian custom regulations’ and there it all was in black and white, up to the minute. He printed it out and his chest all puffed out. As soon as he got home he called me excitedly to say how he had presented the customs officer with this bit of paper and told him how his gifts for his grandkids complied with the letter of it. To which the customs officer replied, ‘Welcome home, Mr Singhal!’ “

Singhal could no doubt point to a multitude of such examples. But what about the less measurable ways that the ease of search has changed our lives? I ask. What about the ways in which it has diminished the excitement of serendipity, the way that it has made the personal experience of a chance encounter with knowledge so much rarer?

Singhal has been working on that. The Knowledge Graph will still return the results it thinks you most likely need, but down the list it will have a randomized element; it will have chance built into it, another way it might mimic the way we think. His current obsession is in behavioral psychology; he has become an avid student of the work of Daniel Kahneman. “I just love the way it details how human beings feel when faced with choices and decisions, what makes you run away when someone offers you 32 chocolates to choose from, but which satisfies you when they only give you one chocolate.”

How, I wonder, will Google incorporate that knowledge in its unending search?

“I don’t know exactly yet …” Singhal says brightly, leaving you in no doubt of what might be his organization’s guiding mantra: he will soon.
