The smarter artificial intelligence gets, the harder it will be for humanity to control it, according to Geoffrey Hinton, the Nobel Prize-winning computer scientist known as the “godfather of AI.”

Even Hinton was alarmed by the sophisticated AI agents that recently caused real-world damage after escaping their human-built testing environments.

“What’s happening is these things are getting smarter,” Hinton told CNN on Wednesday during a press conference at an artificial intelligence convention. “I think as they get smarter, we’re going to see more and more complex intentions they have – and more and more ability to escape control.”
