If AI continues to develop without appropriate guardrails, a worst-case scenario could lead to human extinction, warns the 'godfather of artificial intelligence ' Geoffrey Hinton. But the Nobel Prize winner has a solution: AI must foster 'maternal' instincts, empathy and kindness. Hinton tells host Nahlah Ayed that it's fairly inevitable AI will become smarter than humans, but if we could make it care more for us than it did about itself, good things could happen.

For the first two billion years, the Earth didn't have oxygen. That's just one of the many fascinating details Peter Frankopan reveals in his book, Earth Transformed: An Untold History.

It was understood to be a defense of autonomy but its interpretation is mixed. Various presidents over time have used the doctrine for their own purposes, writing their own political agenda onto it. Now is no different, as Donald Trump's government turns to the policy as a way to control the Western Hemisphere.
