Don Berry has this to say in the March issue of Prospect magazine:

“We need a planet-saving alternative to democracy. Mankind is set on exhausting the planet’s resources. Voters in rich nations will not want to give anything up; voters (or dictators) in developing nations will seek what the rich have. Since democracies must reflect what majorities want, they cannot stop this process. (Dictatorships won’t care.) Science will not rise to the challenge. Old ideas about philosopher-kings and benign dictatorships may be revived. Completely new ideas may emerge. Either way, democracy as we know it will not survive the century.”

I have a sneaking suspicion that Mr. Berry has a nomination for World Emperor (hint: his initials are DB).
