Ray Kurzweil
Kurzweil Curve
Kurzweil stood on the shoulders of geniuses like Newton, Albert Einstein, John von Neumann, and Alan Turing writing The Singularity is Near. He has made 147 predictions since the 1990’s about technology and has an 86% accuracy rate. And the 14% where he says he got it wrong, we personally think he got it mostly right...we’ll give him a pass when he erroneously predicted self driving cars by 2009. He was a year off in predicting when technology would beat the greatest chess player in the world.
Lastly, Kurzweil’s original definition of the Singularity he articulated in The Singularity is Near still holds today. Kurzweil defined the Singularity as:

"... a future period during which the pace of technological change will be so rapid, its impact so deep, that human life will be irreversibly transformed. Although neither utopian nor dystopian, this epoch will transform the concepts that we rely on to give meaning to our lives, from our business models to the cycle of human life, including death itself."
As recently as October 5, 2017, he still stands by his original predictions regarding the dates this will all happen:
“By 2029, computers will have human-level intelligence,” 2029 is the consistent date I have predicted for when an AI will pass a valid Turing test and therefore achieve human levels of intelligence. I have set the date 2045 for the ‘Singularity’ which is when we will multiply our effective intelligence a billion fold by merging with the intelligence we have created.”7
Thank you Ray.
