The Age of Spiratual Machines

I think that what Ray Kurzweil said in his book about the upcoming years with machines and their intelligence is true. I believe that the day that there is no keyboard or mouse is very likely and possible. SOme of the things he talked about may not happen for a while though. Such as microscopic war-fare. But he did say that this would probably happen near the year 2029 so I guess it could be possible by then, give or take a few more years. But I do think that we will see huge advancedments in micro or nano warfare .
