Hawking made the remarks at the Web Summit Technology Conference held in Lisbon, Portugal, saying: 'In theory, computers can simulate and surpass human intelligence.'
Hawking talked about the potential of artificial intelligence to help eliminate damage to the natural world or to eradicate poverty and disease, and every aspect of society will be changed.
But he acknowledged that the future is uncertain.
Hawking said in his speech: 'Successful creation of effective artificial intelligence may be the greatest or worst event in our history of civilization, and we just do not know, so we can not know if we will get the help of artificial intelligence Either ignored by it or destroyed by it.
Unless we learn how to be prepared and avoid potential risks, artificial intelligence may be the worst event in the history of human civilization, with dangers such as powerful automated weapons or new ways of oppressing the majority by the minority. Will bring tremendous damage to our economy. '
Hawking explained that in order to avoid this potential risk, the creators of artificial intelligence need to adopt 'best practices and effective management'.
Hawking stressed that some legislative efforts are under way in Europe, especially since legislators made new provisions on artificial intelligence and robotics earlier this year, and member countries of the European Parliament said that the EU needs to establish a wide range of laws and regulations to solve this problem.
It is because of these developments that Hawking is full of hope for the future.
Hawking said: "I am an optimist and I believe we can create artificial intelligence for the benefit of the world. It can live in harmony with us. We just need to be aware of danger, identify danger, use best practices and management, advance be prepared. '
This is not the first time Hawking has warned against the dangers of artificial intelligence: he talked to many celebrities in the tech industry about their concerns about artificial intelligence technology, and Tesla and SpaceX chief executive Elon Musk recently said that artificial intelligence May lead to World War III and even suggest that humans must be merged with the robot in order to remain relevant in the future.
Still others have come up with ways to deal with artificial intelligence, said Bill Gates, the founder of Microsoft, that robots should pay income tax.
Some big names in the tech industry do not think artificial intelligence will cause the doomsday. "Facebook chief executive Mark Zuckerberg said he is" very optimistic about the future of artificial intelligence. "
