See, we don't even need Terminators; totalitarian regimes of nonhuman actors uninterested in keeping individual humans alive are already here in the form of megacorporations. Most of the top search results for "corporate singularity" have to do with people answering the question "Will corporations prevent the singularity?" But I fear the rise of these human-enslaving corporations is the singularity. The hive mind of corporate culture serves to give these nonhuman entities sentience of a sort, all directed toward the preservation and propagation of the company at all costs. And the worst part is, we volunteer to surrender our minds and our energy to these entities. As my husband puts it, it's the voluntary Matrix.
