That is the onslaught. It has been going on a long time, I argue, but in the 20th century humans have certainly perfected it, extending domination to every single corner of the earth and our Homo sapiens population to more than 6 billion - until no place is untouched by despoliation.

My analysis, especially of the computer revolution, always comes back to capitalism. It's that economic system that has led to Western civilization's willingness to enslave ourselves to machines - because some people benefit enormously from it, while the costs are borne by other people and the planet.

Economic and social misery increases in direct proportion to the size and power of the central government of a nation or state.

Governments, existing primarily to protect and enhance capitalism, maintain their power through the use of technologies that control the populace - by bread or circuses, by war or schooling, by armies and police, all of which are enabled and empowered by technology. That is what we might call the stick part of capitalism, while the riches-for-the-few is the carrot.

I'm convinced that the catastrophes of the next two decades will be so vast as to bring about a world where life, if it survives, will be far simpler - and the technologies, too. Then we will have come full circle to something like life on the savanna.

That is the onslaught. It has been going on a long time, I argue, but in the 20th century humans have certainly perfected it, extending domination to every single corner of the earth and our Homo sapiens population to more than 6 billion - until no place is untouched by despoliation.

I want to leave my country without leaving my home.
