“There’s another particular thing I want to talk about, which is the existential risk of what happens when these things get more intelligent than us.
“We’re biological systems, these are digital systems, and the difference is that with digital systems you have many copies of the same set of weights, the same model of the world.

Dr Hinton has spent his entire career researching the development and uses of AI technologies, and in 2018 received the Turing Award for his work.
Since 2013 he has split his time between Google’s artificial intelligence research team and the University of Toronto, where he is a professor emeritus.
The leading expert, 75, studied experimental psychology at the University of Cambridge before obtaining his PhD in artificial intelligence from Edinburgh University, in 1978.
