Your form of anarchism may be opposed to institutions, but all anarchists (including me) don't agree with that. Institutions are sets of permanent social relations - examples include the family, media, politics, and science. I see nothing inherently wrong with permanent social relations or organisations. Nor is there necessarily wrong with an organisation interested in its own self-preservation. What's wrong with a non-hierarchical agricultural collective (who's purpose is to provide it's members with food) trying to preserve itself?

At least the kind of computers that exist now.

"The beauty of the democratic systems of thought control, as contrasted with their clumsy totalitarian counterparts, is that they operate by subtly establishing on a voluntary basis--aided by the force of nationalism and media control by substantial interests--presuppositions that set the limits of debate, rather than by imposing beliefs with a bludgeon. Then let the debate rage; the more lively and vigorous it is, the better the propaganda system is served, since the presuppositions (U.S. benevolence, lack of rational imperial goals, defensive posture, etc.) are more firmly established. Those who do not accept the fundamental principles of state propaganda are simply excluded from the debate (or if noticed, dismissed as "emotional," "irresponsible," etc.)." - Noam Chomsky
