Since 'anarchist' is a vague word that has been applied to a variety of attitudes, further explanation is needed. The press has gotten its next McMedia serving with the whole Unabomber caper. The Unabomber may have a serious bone to pick with technology, but that in no way makes a person an anarchist. We are anti-authoritarians through and through, and yet, if you read his Manifesto, you see that he is not opposed to authority per se, but merely to authority over him. Anarchists recognize that we cannot exempt ourselves from our own rules, for to do so is to engage in vanguardism, a subtle poison which clouds judgment and ultimately kills revolution by rebuilding elites and authority.
Technology is a tool, nothing else.
If you fail to look beyond the tool, to the hand that wields it, you will be misguided. Environmental degradation, widespread poverty and hunger, nuclear proliferation, and other evils are not merely the result of technology itself. It is profitable for some, so it is carried out, even against the interests of the overwhelming majority of people. This is measured, however, purely in economic terms. Where this occurs, you will see capitalism at work.
