About one-and-a-half minutes into the clip, the narrator says that “he [Kurzweil] believes that our understanding of the human brain will soon be complete.”
Although this is not a direct quote from Kurzweil himself, he does actually believe this. It is true that advances in our understanding of the brain are coming thick and fast. But I’m certain pretty sure that we’ll never fully understand the brain, and think that Kurzweil’s claim is utterly ridiculous.
