Re: political life on Earth
Depends on the consequences of countries NOT developing a democratic process. A lot of people believe the USSR collapsed because its system of government and economy was unnatural and couldn't compete with the "fitter" democratic capitalist countries.
I do think decentralization of power will be a major movement in this century, because of the clumsiness of bureaucracies and the spread of information. Centralized authority maintains its mystique through secrecy and hoarding of connections, but distribution of information renders much of that mystique impossible to maintain. Once "the masses" get it into their heads that they can be as smart as those in power, centralized authority has trouble keeping outsiders out and insiders in.
