This week; if a celebrity retweets you, would that have more emotional impact than a birthday card from your mother? Do you get upset when your close friends don’t like some of your Facebook updates? Do you constantly have to dodge people staring down at their smartphones? One person who is looking at how technology changes our behaviour and values for better, or worse, is Prof Shannon Vallor. She was in town to deliver a lecture at Trinity College this week and Niall Kitson caught up with her, to find out her thoughts on how technology can help us live not just more productive lives, but more ethical ones, too.
