Artificial intelligence fears remain the stuff of sci-fi fantasy

Prominent scientists including Stephen Hawking and tech billionaire Elon Musk are among the signatories to an open letter warning of the dangers of artificial intelligence - known more simply as AI.

But one robotics expert told ITV News that today's cutting-edge machines are best used for "dull, dirty and dangerous" work, such as robot submarines repairing oil well leaks.

Another said even the most advanced computer was "no more intelligent" than a mouse - and even that might be "an exaggeration".
