Of course I understand why people WANT to have a description of the sustainable life of the future. They think this would enable them to adopt that sustainable life NOW, TODAY. But social change doesn’t come about that way, any more than technological change does. It would have been useless to show Charles Babbage a printed circuit or to show Thomas Edison a transistor. They could have done nothing with those things in their day–and we could do nothing today with a picture life a hundred years from now. The future is not something that can be planned hundreds of years in advance–or even ten years in advance. Adolf Hitler’s Thousand Year Reich didn’t even last a thousand WEEKS. There has never been a plan for the future–and there never will be.
