Green is no goal

"To achieve a sufficiently large but distant win, it is worth sacrificing a much smaller but nearer win if it stands in the way or distracts and delays the larger achievement. To achieve a small but near win, it is not worth sacrificing a much larger but more distant win. But the difference in magnitude must be sufficiently large, and the difference in distance sufficiently small, to make delaying the gratification really pay off. Speculation and argument over the sizes and distances and relative probabilities of success and incompatibilities of the competing achievements fuel many a political argument. Like "green" open access....Why spend time designing a better horse shoe when you could be inventing the railway train?..."
