Brian Greene on AI: 'Biological life on Earth could be a stepping stone'

Want to understand string theory in 20 minutes? The theoretical physicist has the handy knack of explaining the seemingly unexplainable, taking science out of its academic comfort-zone and into the general public. As co-founder of the yearly World Science Festival, Greene is passionate about increasing public awareness of not just the important of science but also its power to inspire us. He speaks to WIRED about how AI might replace biological life on Earth, the post-truth twilight zone and the challenge of computing consciousness. And we used to do all calculations with a pencil and paper, before that we did it scratching it out on tablets, but as technology progresses we have ever more powerful tools. I would say the same thing about AI, it's something that we can harness in order that we can do our jobs better.
