Here's some more from author and scientist David Brin, a very smart man.
many of our machines consume copious resources, exactly as a human servant would. Hence the multiplier effect of how vastly more resource-hungry an american household is, compared to others around the world. For this reason, we are behooved, obligated, to expend a large portion of our surplus on research to make all servant machines vastly more efficient. Only thus could it ever be possible for everyone on the planet to enter the diamond-pinnacle of citizen-humans, living in relative decency.
And he goes on to say...
In fact, modernism should impel any reasonable person to pull out the stops on efficiency research, almost above any other priority. It should be the top imperative, a goal driven by sure knowledge that our childrens' lives and comfort will depend on vastly muliplying wealth while reducing resource impact by two orders of magnitude. There should be a dozen "Manhattan Projects" aimed at achiving this sustainability goal - including the resumption of building modern and improved nuclear power plants. (Aha! Brin swerves and delivers a kick to the LEFT!)
