We're also facing a climate and pollutant crisis as a species so we seem only capable of thinking in the short term. We're not doing that well right now after only a brief period of industrialisation.
Yes, so let's think long term. How do we keep it rolling? Perhaps we will need to continue to advance our technology, especially moving industries to space where there is no ecosphere.
