Looking forward is important, but looking too far forward assumes that your vision of the future matches reality and that’s just plain narcissism. How much we can accurately predict what the world will look like in the future is a direct function of how far into the future we are looking. Accuracy sharply drops off after even just a few years. Predictions made via science, such as the temperature of the earth with historical and current decisions/energy production is a lot more useful than hypothesizing about how humans might live. Using these assumptions as a starting point for making decisions about how to plan/exist today rather than using predictions made via science to inform a course to not continue or change from are vastly different decisions and the author brings up a good point about the intermixing and equivocating of the two.
