Forty years ago, Apple changed the world when they launched the Macintosh computer, with a superbowl ad echoing Orwell’s 1984. So the story goes anyway. Reading that (really very good!) piece from Siva Vaidhyanathan in the Guardian this morning, I was struck as I so often am by the declaratory confidence of the headline. WORLD CHANGED; MACHINE LAUNCHED. Vaidhyanathan layers it on, claiming that the launch could be seen as ‘the beginning of the long 21st century’. It struck me in reading that we are now starting to see the end of the twentieth century as a historical phenomenon, and writing about it in a way that seeks consistency and consensus, in the same way as there is consensus about the rest of history as we have learned it – that there were two world wars in the 20th century, that the Cold War was between America and Russia, that the EU was formally launched in 1993, and so on. In structuring history, we superimpose salience upon people, and events, that may not have been obvious at the time, and that possibly misshapes our understanding of the world we live in today.
