Sometimes the House of Lords throws out speeches so interesting and radical, that you simply cannot imagine them being made in the Commons. One such came this week from the neuro-biologist Susan Greenfield. She asked a question that affects all of us, yet which I have never heard discussed by mainstream politicians: is technology changing our brains?
The context is the clicking, bleeping, flashing world of screens. There has been a change in our environment that is so all-embracing and in a way so banal that we barely notice it. In just a couple of decades, we have slipped away from a culture based essentially on words to one based essentially on images, or pictures. This is probably one of the great shifts in the story of modern humans but we take it almost for granted.
