Physicist Stephen Hawking reportedly warns that artificial intelligence (AI) could be the "worst event in the history of our civilization."
He urged creators of AI to "employ best practice and effective management," CNBC cited him as saying.
Hawking, a British cosmologist who was diagnosed with motor neuron disease aged 21, said technology could transform every aspect of life but cautioned that artificial intelligence poses new challenges.
He did say that technology can hopefully reverse some of the harm caused to the planet by industrialization and help end disease and poverty, Reuters reported.
He said artificial intelligence and robots are already threatening millions of jobs - but this new revolution could be used to help society and for the good of the world such as alleviating poverty and disease.
