In the London Review of Books, Daniel Soar writes:

This spring, the billionaire Eric Schmidt announced that there were only four really significant technology companies: Apple, Amazon, Facebook and Google, the company he had until recently been running. People believed him. What distinguished his new ‘gang of four’ from the generation it had superseded – companies like Intel, Microsoft, Dell and Cisco, which mostly exist to sell gizmos and gadgets and innumerable hours of expensive support services to corporate clients – was that the newcomers sold their products and services to ordinary people. Since there are more ordinary people in the world than there are businesses, and since there’s nothing that ordinary people don’t want or need, or can’t be persuaded they want or need when it flashes up alluringly on their screens, the money to be made from them is virtually limitless. Together, Schmidt’s four companies are worth more than half a trillion dollars. The technology sector isn’t as big as, say, oil, but it’s growing, as more and more traditional industries – advertising, travel, real estate, used cars, new cars, porn, television, film, music, publishing, news – are subsumed into the digital economy. Schmidt, who as the ex-CEO of a multibillion-dollar corporation had learned to take the long view, warned that not all four of his disruptive gang could survive. So – as they all converge from their various beginnings to compete in the same area, the place usually referred to as ‘the cloud’, a place where everything that matters is online – the question is: who will be the first to blink?

If the company that falters is Google, it won’t be because it didn’t see the future coming. Of Schmidt’s four technology juggernauts, Google has always been the most ambitious, and the most committed to getting everything possible onto the internet, its mission being ‘to organise the world’s information and make it universally accessible and useful’. Its ubiquitous search box has changed the way information can be got at to such an extent that ten years after most people first learned of its existence you wouldn’t think of trying to find out anything without typing it into Google first. Searching on Google is automatic, a reflex, just part of what we do. But an insufficiently thought-about fact is that in order to organise the world’s information Google first has to get hold of the stuff. And in the long run ‘the world’s information’ means much more than anyone would ever have imagined it could. It means, of course, the totality of the information contained on the World Wide Web, or the contents of more than a trillion webpages (it was a trillion at the last count, in 2008; now, such a number would be meaningless). But that much goes without saying, since indexing and ranking webpages is where Google began when it got going as a research project at Stanford in 1996, just five years after the web itself was invented. It means – or would mean, if lawyers let Google have its way – the complete contents of every one of the more than 33 million books in the Library of Congress or, if you include slightly varying editions and pamphlets and other ephemera, the contents of the approximately 129,864,880 books published in every recorded language since printing was invented. It means every video uploaded to the public internet, a quantity – if you take the Google-owned YouTube alone – that is increasing at the rate of nearly an hour of video every second.

It means the location of businesses, religious institutions, schools, libraries, community centres and hospitals worldwide – a global Yellow Pages. It means the inventories of shops, the archives of newspapers, the minute by minute performance of the stock market. It means, or will mean, if Google keeps going, the exact look of every street corner and roadside on the planet, photographed in high resolution and kept as up to date as possible: the logic, if not yet the practice, of Google Street View, means that city streets should be under ever more regular photographic surveillance, since the fresher and more complete the imagery the more useful people will find it, and the more they will therefore use it. If it doesn’t already have a piece of data, you can be sure that Google is pursuing a way of getting it, of gathering and sorting every kind of public information there is.

But all this is just the stuff that Google makes publicly searchable, or ‘universally accessible’. It’s only a small fraction of the information it actually possesses. I know that Google knows, because I’ve looked it up, that on 30 April 2011 at 4.33 p.m. I was at Willesden Junction station, travelling west. It knows where I was, as it knows where I am now, because like many millions of others I have an Android-powered smartphone with Google’s location service turned on. If you use the full range of its products, Google knows the identity of everyone you communicate with by email, instant messaging and phone, with a master list – accessible only by you, and by Google – of the people you contact most. If you use its products, Google knows the content of your emails and voicemail messages (a feature of Google Voice is that it transcribes messages and emails them to you, storing the text on Google servers indefinitely). If you find Google products compelling – and their promise of access-anywhere, conflagration and laptop-theft-proof document creation makes them quite compelling – Google knows the content of every document you write or spreadsheet you fiddle or presentation you construct. If as many Google-enabled robotic devices get installed as Google hopes, Google may soon know the contents of your fridge, your heart rate when you’re exercising, the weather outside your front door, the pattern of electricity use in your home.
