Paul Chefurka wrote an excellent analysis of his vision of a very rocky future. My only critique of his work is the possibility that advanced batteries could store nuclear-generated electricity for the purposes of farming and distributing food. The use of nuclear-powered batteries would require a relatively high degree of human intelligence, which is not what our world is currently producing.
