The world is changing fast. The dust has barely settled on the digital revolution and now we have to strap ourselves in for another certain thrust into the unknown: the material revolution. Look at 3D printing, for example. They're talking about being able to print human organs in the not-too-distant future. They're going to be printing KIDNEYS! What's it all about? When is it coming? Will I be able to sit this one out? Guy Rundle talks to the who's who in this mind-bogglingly new world, and paints a vivid picture of how life will change throughout the 21st century when emerging technologies like this become mainstream. There will be enormous implications not just for Australia but for the global economy, international relations and the fundamental structures of our lives.
