Is your brain being altered due to our increasing reliance on search engines, social networking sites and other digital technologies? That is the question I  posed at last year”s 3D Bar Camp in Limerick. It is a subject I am increasingly becoming involved in and so I was interested to see this video from Nicholas Carr, author of  the best-selling book “The Big Switch: Rewiring the World, from Edison to Google,” and “”The Shallows: What the Internet Is Doing to Our Brains”, a book I referred to in my talk.
