Michael Anissimov argues that much 'Singularity' discussion is already fuzzing out into meaninglessness. The evident tendency of many commentators to get side-tracked by tedious neo-humanist fantasies (typically mixing immortalism with virtual-sex scenarios) certainly supports his case.
Rigorously conceived Singularity is Intelligence Catastrophe: the punctual emergence of explosively self-regenerating post-human cognitive amplification on the curve of accelerating technology -- aka Planetary Meltdown, the Immanent Limit of Capitalism, or the Wall Across the Future (where human imagination terminates).
Isn't it?
