There's a most excellent vintage 1980s lecture by Robert Anton Wilson titled "The Jumping Jesus Phenomenon". The gist of it can be found at the rawilson.com website as well as elsewhere. Wilson defines the "jesus" (small j) as the number of scientific facts known at the time of Jesus. Then he goes on to count how many years it takes to double that number. By his count, humanity accumulated 2j by about the year 1500. Then 4j by the year 1750, and so on. I forget the exact numbers but the point of the lecture was that our j-factor was increasing at an ever-increasing rate. By Wilson's estimation the curve would go vertical sometime around ... wait for it ... the year 2012. This reads a lot like Kurzweil's singularity hypothesis (among others) but I'm not sure who developed the concept first.
