2010 was very cyberpunk. All that was missing was Wintermute.
I'm here!
More seriously, the formation/actions of Anonymous remind me of the stand alone complexes (more formally termed "second-order simulacra," in semiotics) from Ghost in the Shell, one of the greatest cyberpunk anime series out there. It's astonishing that Shiro Masamune was able to predict this occurence as a result of the growth of the internet, and even more astonishing that it happened ~20 years before he predicted, prior to the existence of cyberbrains or synthetic "ghosts."
I guess what I'm saying is, Anonymous is the cumulative effect of these strong memes on human brains. The Ghost in the Shell is on a substrate of part-internet, part-human.
