Quoting:
"Renowned physicist Stephen Hawking has warned that the rise of artificial intelligence could become "the worst event in the history of our civilization" unless humanity is prepared for the potential risks that come with it.
During a speech at the opening night of the Web Summit conference in Lisbon, Portugal on Monday (6 November), Hawking said effective AI could bring a host of societal benefits and transformation for mankind, noting that "computers can, in theory, emulate human intelligence and exceed it.""
