of our brains to a computer. >> in the future you think we'll be able to upload our thoughts? >> i think we're already there because our thinking is augmented with our technology. we now wear this kind of on our bodies. and this is intelligent. you can translate languages. you can access all of human knowledge. it is an indirect connection from our brain to the cloud. 100 years from now people will think it was amazing when we went throughout the day without backing up our mind file. if our thinking is partly biological and partly nonbiological, the nonbiological part is expanding exponentially. it's doubling in power every year. according to my calculations, by 2045, we will multiply our intelligence a billionfold. the nonbiological part is going to dominate. >> that's amazing. >> that's such a profound transformation that we borrowed this metaphor from physics. >> that's the singularity. >> right. >> kurzweil's calculations predict the singularity will hit in 2045, a time when man and machine will be so connected that we will be able to transcend the limits of biology once and for all.
