If there's still somebody who thinks that the word "Singularity" hasn't lost all meaning, look no further than this paper:
We agree with Vinge's suggestion for naming events that are “capable of rupturing the fabric of human history” (or leading to profound societal changes) as a “singularity” [...] In this paper, we consider two past singularities (arguably with important enough social change to qualify) [...]. The globalization occurring under Portuguese leadership of maritime empire building and naval technological progress is characterized by a metric describing diffusion. The revolution in time keeping, on the other hand, is characterized by a technological capability metric.
If it's worth saying, but not worth its own post, even in Discussion, it goes here.
