This is a very good documentary called Transcendent Man. It's about Ray Kurzweil. This man is a real-life David Sarif.
I think the doc. can be found on youtube, if not, it's for sure on Amazon Prime.

Excellent documentary, watched this not long ago and would definitely recommend it for anyone interested in this 'singularity' idea.
The movie Transcendence which is coming out soon is based on his ideas from this documentary.
For those who haven't seen the doco, it talks about humans and machines becoming one in just 20 years time, considering how fast technology is moving in this day and age. Ray talks about technology becoming the size of blood cells, in which we will inject. He also believes that in just 40 years time we will have something that makes us live forever.
It also discusses the fact that his ideas may be ridiculous and if this were to happen, it could start a war with people who are anti-singularity.
Definitely an interesting watch.
