The Technical Singularity

When do you think the technical singularity will hit?  I believe it will occur around the year 2045. I think evidence for this will really pile on in about 10-15 years.  As soon as a hand held device has the power of the human brain, it will be further evidence that this singularity is in the future. Hopefully the evolution of truly intelligent devices will jump start this process, for this is likely the only way it will happen.
