22 Vision: babble It may be hard to remember, but there used to be a time when you didn't know what all your friends were up to. You couldn't ring them on their mobile wherever they might be. You couldn't swap endless text messages to while away an afternoon, or agree where best to meet up after you'd left the house. You couldn't repeatedly update status messages about what you were having for lunch or what you thought of that last kick in the football, let alone simultaneously read what everyone else was doing too. As recently as the year 2000 most people's lives were closed and private, and most definitely not Googleable or shared or broadcast. Expect the barriers to tumble even faster by 2020. We'll be firing off updates left right and centre, both intentionally and unintentionally, as technology enables the broadcast of everything around us. Specific location, emotional state, video livestream, all freely available to anyone who cares to look. Advertisers will have a field day, friends will become absorbed in an addictive web of data, and stalkers will never have had it so easy. We older folk may hold back because we still value the dignity of privacy, but an entire generation will have embraced a 24/7 transmission of their existence. Join in, or be nobody.
