An anonymous reader shares a USA Today report: Elon Musk isn't the only high-profile figure concerned about the rise of artificial intelligence. Scientist Stephen Hawking warned AI could serve as the "worst event in the history of our civilization" unless humanity is prepared for its possible risks. Hawking made the remarks during the opening night of the Web Summit in Lisbon, Portugal. Hawking expects AI to transform every part of our lives, with the potential to undo damage done to the Earth and cure diseases. However, Hawking said AI could also spur the creation of powerful autonomous weapons of terror that could be used as a tool "by the few to oppress the many." "Success in creating effective AI could be the biggest event in the history of our civilization, or the worst," he said. Hawking called for more research in AI on how to best use the technology, as well as implored scientists to think about AI's impact. "Perhaps we should all stop for a moment and focus our thinking on not only making AI more capable and successful, but maximizing its societal benefit," he said.
