Since the dawn of civilisation, mankind has been obsessed by the possibility that it will one day be extinguished. The impact of an asteroid on earth and the spectre of nuclear holocaust are the most prevalent millenarian fears of our age. But some scientists are increasingly of the view that a new nightmare must be added to the list. Their concern is that intelligent computers will eventually develop minds of their own and destroy the human race.
The latest warning comes from Professor Stephen Hawking, the renowned astrophysicist who has motor neurone disease. He told an interviewer this week that artificial intelligence could “outsmart us all” and that there is a “near certainty” of technological catastrophe. Most non-experts will dismiss his claims as a fantasy rooted in science fiction. But the pace of progress in artificial intelligence, or AI, means policy makers should already be considering the social consequences.
The idea that machines might one day be capable of thinking like people has been loosely discussed since the dawn of computing in the 1950s. The huge amount of cash being poured into AI research by US technology companies, together with the exponential growth in computer power, means startling predictions are now being made.
