Not sure if the book also did super exp lines, but the graphs in the singularity is near also have various issues that never got to much deep thought.
Always found it funny that the book admits basically (no direct quote): "sure tech follows an S-curve normally, and that looks exponential at first, but if you take the rate of all historic new techs together on a timeline that clearly is exponential".
And I just thought, you cant know if it is, thats the point with the S-curve as well, and it messes people up. (Like Disco Stew from the Simpsons), and your N=1, it might not even be a S-curve, it could just have a sudden ceiling.
Despite wanting to believe, I was less convinced. (also, not sure if it was just my copy but Yudkowsky's name was spelled wrong, still looking for somebody who has a physical copy who is willing to check for me if that was also in print or just a pdf error)
Back to the subject, a course in business management would have also helped here.
