In Felix Salmon’s critique of Dave Eggers’ new novel, he writes glowingly of “It Knows,” Daniel Soar’s 2011 London Review of Books piece about three volumes regarding Google and the place of the Plex in our world. (Or is it our place in the Plex’s world?) A passage about the late GOOG-411 service:

“Levy tells the story of a new recruit with a long managerial background who asked Google’s senior vice-president of engineering, Alan Eustace, what systems Google had in place to improve its products. ‘He expected to hear about quality assurance teams and focus groups’ – the sort of set-up he was used to. ‘Instead Eustace explained that Google’s brain was like a baby’s, an omnivorous sponge that was always getting smarter from the information it soaked up.’ Like a baby, Google uses what it hears to learn about the workings of human language. The large number of people who search for ‘pictures of dogs’ and also ‘pictures of puppies’ tells Google that ‘puppy’ and ‘dog’ mean similar things, yet it also knows that people searching for ‘hot dogs’ get cross if they’re given instructions for ‘boiling puppies’. If Google misunderstands you, and delivers the wrong results, the fact that you’ll go back and rephrase your query, explaining what you mean, will help it get it right next time. Every search for information is itself a piece of information Google can learn from.

By 2007, Google knew enough about the structure of queries to be able to release a US-only directory inquiry service called GOOG-411. You dialled 1-800-4664-411 and spoke your question to the robot operator, which parsed it and spoke you back the top eight results, while offering to connect your call. It was free, nifty and widely used, especially because – unprecedentedly for a company that had never spent much on marketing – Google chose to promote it on billboards across California and New York State. People thought it was weird that Google was paying to advertise a product it couldn’t possibly make money from, but by then Google had become known for doing weird and pleasing things. In 2004, it launched Gmail with what was for the time an insanely large quota of free storage – 1GB, five hundred times more than its competitors. But in that case it was making money from the ads that appeared alongside your emails. What was it getting with GOOG-411? It soon became clear that what it was getting were demands for pizza spoken in every accent in the continental United States, along with questions about plumbers in Detroit and countless variations on the pronunciations of ‘Schenectady’, ‘Okefenokee’ and ‘Boca Raton’. GOOG-411, a Google researcher later wrote, was a phoneme-gathering operation, a way of improving voice recognition technology through massive data collection.

Three years later, the service was dropped, but by then Google had launched its Android operating system and had released into the wild an improved search-by-voice service that didn’t require a phone call. You tapped the little microphone icon on your phone’s screen – it was later extended to Blackberries and iPhones – and your speech was transmitted via the mobile internet to Google servers, where it was interpreted using the advanced techniques the GOOG-411 exercise had enabled. The baby had learned to talk. Now that Android phones are being activated at a rate of more than half a million a day,​4 Google suddenly has a vast and growing repository of spoken words, in every language on earth, and a much more powerful learning machine.”
