One part biography, one part brain food; as an appetizer to the thought path of noted futurist Ray Kurzweil, it can be difficult at times to separate fact from fragment over the course of this documentary. Kurzweil's favorite subject is one of increasing relevance, perhaps even by the minute: he seeks to pinpoint the moment of so-called "singularity," when mankind's built-in body chemistry will finally cross the line into his rapidly-developing technological and biological know-how. In short - how soon will we be able to back up our thoughts and feelings to an external hard drive, what sort of moral and philosophical arguments will be made for and against the practice, and where will the ball of wax roll after that debate is behind us?

Though its post-production effects can get a bit over-the-top at times, reminding viewers more than once of the over-ambitious "world of tomorrow" predictions popular in the 1950s, the film is largely successful at fostering a curious sort of fascination with our current point in history and the staggering number of possibilities present within our lifetime. Kurzweil himself is to thank for much of that, as his smooth, relaxed speaking gives the impression that anything is possible, even if (as some of his detractors point out during the film's apex) he completely overlooks humanity's tendency to use such moments for evil causes as well as good. Intensely interesting stuff that effectively sows the seeds of conception.
