Sebastian Faulks said this quote

I suppose it was a dream that lasted really about fifty years. By the time universal education had begun to work properly, say 1925, and the time the first teachers started to hold back information, say 1975. So a fifty-year dream.I think what's happened is that because they themselves know less than their predecessors, innovators and leaders today have remade the world in their own image. Spellchecks. Search engines. They've remodeled the world so that ignorance is not really a disadvantage. And I should think that increasingly they'll carry on reshaping the world to accommodate a net loss of knowledge.
