According to Jacobs, human civilization is doomed because of decay in five "pillars" of society. Community is threatened by consumerism. Education is threatened by institutions. Science is threatened by politics. Government are threatened by lobbyists. And culture is threatened by a lack of community resources. The eventual result of this decay will be a future 'dark age' characterized by mass amnesia.
