The demand side of innovation has been highlighted many times in the past. As Liebenstein put it "The knowledge may have been there already and a change in circumstances induced the change in technique". More generally the Boserup hypothesis sets out how agricultural innovation is driven by increasing population densities. Adam Smith made the same point in his discussion of agriculture in the American colonies. That these ideas not widely known, or just forgotten, reflects how much more attractive people find the silver bullet, hero-inventor story of innovation. And how much more useful those ideas are for politicians.
