This title cuts through the hype of the internet revolution without denouncing its significance, it assesses the true nature of the intangible economy and shows that the changes in the world go right to the heart of economics - since what is changing is the very source of value and how it changes over time. The world is on the brink of another leap forward in productive capacity and wealth which is the equivalent of the transformation which took place in our lives with the industrial revolution and the discovery of North America rolled into one - and collapsed into a couple of decades. The results may be a change in our circumstances which will make our lives today every bit as incongruous to the next generation as those of two hundred years ago are to us.
