This classic of prediction, written in 1969, has now been brought up to date, the prophecies judges, and the omens extended to 2030.The success rate of Jencks' forecasts and his method of combining expert prediction with structural analysis make this book an important contribution to the art of conjecture. Not only did he predict the a series of innovations that have changed the world, such as the Internet, but he identified six main architectural traditions that continuously transform over time. This provides a method of gauging what are likely to be the future movements in architecture, a useful and fascinating tool for speculation. No other book of forecasting is like it, a hypertext of retrospection, judgement and further prophecy.
