Posthuman Blues

"Increasing technological autonomy, however we choose to measure it, is one key assumption behind the singularity hypothesis. Were it to be proven incorrect in coming years, singularity models would have to be fundamentally revised. However, data to date give every indication that autonomy is dramatically increasing every year. Writers on the singularity topic now suggest that progressively more human-independent computer evolution must eventually transition to a 'runaway positive feedback loop' in high-level machine computation, from our perspective."
