People seem to vastly oversimplify Kurzweil's (and others) stance on the singularity. The truth is that we don't know what will happen. The best one can do is prepare for possible senarios.
I tried to locate a link to them for this post but TechNetCast seems no more and DDJ's site doesn't bear fruit either. If anyone here knows where they might be found please share -- they are definitely worth the time.
Since then, Kurzweil has certainly pursued his beliefs (books, speeches, press, etc.) with these graduates being the latest expression of those ideas.

I then read The Singularity is Near.
I tend to agree more with Eliezer Yudkowsky and Michael Anissimov than Kurzweil about this stuff, but the video above is still worth watching (much much better than his TED video, which was too short to allow him to make his main points).
