Yes, true, the level and timeline are very very different, whether we call the difference qualitative or quantitative.
I guess I considered it quantitative because when I was 20 I was already thinking there was at least a possibility of seeing human extinction or immortality in my lifetime, though my probabilities and timelines are now hugely different. Extinction has seemed like a possibility since the Cold War, and IIRC Kurzweil started talking about the singularity in the 90s.
