Artificial intelligence will become strong enough to be a concern, says Bill Gates

Bill Gates is the latest prominent figure from the technology industry to express concern about the future evolution of artificial intelligence, although he thinks it will be "decades" before super-intelligent machines pose a threat to humans. He joins Elon Musk and Stephen Hawking in suggesting that the march of AI could be an existential threat to humans. The former Microsoft boss gave his opinion during his latest Ask Me Anything (AMA) interview on the Reddit networking site. "I am in the camp that is concerned about super intelligence. First the machines will do a lot of jobs for us and not be super-intelligent. That should be positive if we manage it well," wrote Gates.
