What about neural models for Web 3.0, the Semantic Web as a kind of geocortex where decentralized, independent, and diverse individuals play the role of neurons, aggregating and firing linguistic, subject-oriented action potentials through their many untethered screens, ultimately producing a potentially superhuman collective intelligence a la The Wisdom of Crowds? The neocortex produces the self. Might not a Semantic Web modeled after the neocortex in time produce something like a singular planetary self? What might the impact of such a singularity be on planetary emergencies like climate change, famine, terrorism, WMDs, mass extinction, and the creation of a sustainable, peaceful world? Could it be possible that a planetary self is necessary, even essential to managing and controlling a mature (i.e., fully populated) planetary body?
