And even technological progress only happens when its products can in some way be used for the diminution of human liberty. In all the useful arts, the world is either standing still or going backwards.' And the very medium of thought, in Orwell’s reckoning, language, would be crippled. Winston’s co-worker, employed in the project, explains: 'Do you know that Newspeak is the only language in the world whose vocabulary gets smaller every year? … In the end we will make thoughtcrime literally impossible, because there will be no words in which to express it.' What actually happened?... This logarithmic graph shows that in 1948, the Encyclopaedia Britannica was about 29,000 pages. Its final printed edition, in 2010, had 33,000. Today most of us rely on Wikipedia (despite its occasional errors and editing wars), which as of last year had the equivalent of 3.2 million Britannica pages, a hundredfold increase...."
