If anyone's seen the film WALLE, you'll know it features a space-ship housing people who have become so reliant on technology they never see anything beyond a screen suspended in front of their face. I'd like to think we're a long way away from that, but you only have to notice a person sauntering along the pavement, eyes glued to their latest smartphone, and it doesn't seem that far away. I'm not a Luddite, but I do worry what kind of world digital technology is taking us into: if in future to "like" something won't be an emotional response, but a physical act of clicking a tab; if to "chat" will only mean to type into a small window with a postage stamp-sized photo of your friend in the top right-hand corner.
I once went to see comedian Ed Byrne at Birmingham Symphony Hall. As he performed, a woman near the front recorded his routine with her camera phone. "That's right Love," he said noticing her, "watch it on a tiny screen when you get home, then you'll enjoy it." Ed, I salute you.
