How close is the Science of Singularity

As we delved into the issue of Singularity in class today I began to wonder how valid some of the assumptions made by the author were. Were the authors estimates correct or had the author been caught up by the promise of the science and had accelerated the possibility of its eventuality.

To answer this question one should revisit 1989. When I look back twenty years ago I realize that much has not changed. The basic structure of my life has not been altered in any drastic manner. Sure, now I have easy access to computers and the internet. However, beyond the advent of the information age there has been little change for humans as they go about their daily lives. It is therefore my belief that the merger of nanotechnology, genetics and AI will dramatically change the way we live our lives but I am convinced that the merger of the sciences are at least two generations away and not 20-25 years as is the authors contention.
