Again, I really recommend that you read The Singularity is Near before arguing against it (actually not sure if you are arguing against it anymore). But one of the topics there is a long argument on how the pace of change is increasing.
(Eg compare the difference in life between someone born in the 13th century to someone born in the 14th century - not much of a difference. But compare how life have changed in just the last 50 years).
