Have you seen the film 'Transcendent Man' by any chance? It's a documentary on the very subject of immortality.
An excellent documentary as well. Informative, and interesting. Seeing Kurzweil talk about reviving his dead father through a computer was one of the oddest, saddest things I've seen in film. He's a man who literally believes he can bring his father back from the dead--amazing. Another part of the film I found extremely interesting was where one of the interviewees talk about how doomsday, religious end of days, or singularity predictors all seem to place their predictions within their lifetime--an example I've heard a lot about is Mormon prophert Joseph Smith predicting the second coming of Jesus in the mid 1800s (during which Smith would have been alive had he not been killed). It creates an interesting emotional level to Kurzweil's science--is he drawing conclusions from data that doesn't point to what he says it does, holding out for his father's reincarnation?
