4 dangers that most worry AI pioneer Geoffrey Hinton

Geoffrey Hinton, a computer scientist known as the “godfather of artificial intelligence,” recently resigned his high-profile job at Google specifically to share his concerns that unchecked AI development could threaten humanity. It's a big switch for an award-winning researcher who helped pioneer critical AI technologies such as neural networks and “deep learning,” the process AI systems use to absorb and apply new information. In recent interviews, Hinton said his change of heart reflects AI's rapidly growing intelligence and the various ways such systems might upend — or simply end — humanity.
