Arguably, the more personally invested in a problem you become, the more you have to fear from a miracle solution. Say, for instance, you are a recent university graduate intensely concerned with climate change. If, a couple of years from now, someone develops a machine that can turn atmospheric carbon dioxide into oxygen and diamonds for ten dollars a tonne, you will probably be hugely relieved and excited. In one swoop, we would have dealt with climate change, while also providing a lot of very strong building material for ourselves. All hail The Diamond Age.
While I cannot speak from experience, it does seem as though the same development would appear quite different from the perspective of someone who has spent a whole career dealing with climate change, using conventional technologies, and who suddenly finds themselves confronted by this curveball. Certainly, there would be some who rejoiced with all the enthusiasm of the newbies. Others might feel redundant or even cheated, perhaps quite legitimately.
In some ways, this speculation reduces to the fact that humanity rarely, if ever, faces problems that are both multi-generational and wholly deliberate. The development of stone tools was multi-generational, but it wasn’t terribly strategic or deliberate at that timescale. Similarly, post-WWII reconstruction was strategic and directed, but did not really span across multi-dimensional time. At least, not in the same way that climate change probably will. Based on the relatively conservative projection of current trends of technological development, energy use, and human population, it may well be the case that complete and permanent carbon neutrality takes several hundred years to achieve.
Given the risks that exist, we need to commit ourselves to the long haul process of carbon neutrality the difficult way, while retaining the flexibility to adopt a less challenging path, should it be presented to us. That combination of flexibility, determination, and objective evaluation will be a difficult thing to develop and maintain.
