Singularity will be a reality in less than 20 years, Kurzweil estimates that the Singularity will happen in the year 2045, I believe it will come even sooner than that.

The first industrial robot, Unimate, first arrived on the GM assembly line in 1962, welding auto bodies together. At current rate of innovation even Doctors will be out of a job soon. Let's hope we can replace Politicians even sooner!
