I adore my iPad. When I was a teenager many years ago now, I thought the future would be about cars that flew and shiny silver clothing, I couldn't imagine the internet or mobile phones, or indeed microwaves although Star Trek imagined a version of this. The iPad is what I imagined the future would be about, magical machines that transform your life and way of thinking. My only concern now is that although I use all this technology, I have no idea how it works, i could not build any of these machines myself, and I feel vulnerable at times when something goes wrong or more often these days gets stuck. Fortunately I have a son who can help, but the older generation is now reliant on the younger generation to explain how to use complex technology and machines. So much for wisdom and passing down our knowledge, knowledge is moving in the opposite direction from teenagers to us oldies.
