It’s a post on his blog. I’m not sure anybody asked him, or paid him (any more than he gets paid for ads on his blog) to write it. At least, I don’t see any evidence of that. He’s just commenting on a movie that was apparently partially inspired by his own work on the singularity.
I remember reading Kurzweil’s “Age of Spiritual Machines” back when Our Lady Peace released the album inspired by it. I also remember it being VERY HARD TO GET THROUGH.
