In 1962 the French weekly l'Express postulated about a technologically advanced utopia in the year 2000.
By the year 2000 all food will be completely synthetic. Agriculture and fisheries will have become superfluous. The world's population will by then have increased fourfold but will have stabilized. Sea water and ordinary rocks will yield all the necessary metals. Disease, as well as famine, will have been eliminated; and universal hygienic inspection and control will have been introduced. The problems of energy production will by then be completely resolved.
From the essay Food - the great challenge of this crucial century by Georg Borgstrom in the 1975 book Notes for the Future: An Alterative History of the Past Decade.
