The book (The singularity is near), which serves as the basis for the movie is one of the most thought provoking reads I have had in a long time.
He looks at various trends throughout history (like Moore's Law) which follow an exponential curve, and he extrapolates the curve into the future.
There may be some arm waving here and there, but there is definitely something to his theories.
Summary: "Most people overestimate what can be accomplished in the short term and underestimate what can be accomplished in the long term".
