For years Steve Wozniak dismissed claims that technology, and particularly artificial intelligence, could threaten humans.
But in a recent interview, the 64-year-old admitted he can now see some of the predictions coming true and that human-like computers could be a dangerous reality.
He even quipped: 'Will we be the gods? Will we be the family pets? Or will we be ants that get stepped on? I don't know.'
The Apple co-founder made the comments during an interview with Paul Smith at Australian Financial Review.
He said: 'Computers are going to take over from humans, no question. If we build these devices to take care of everything for us, eventually they'll think faster than us and they'll get rid of the slow humans to run companies more efficiently.
He directly referenced warnings issued by both Elon Musk and Stephen Hawking about the threat AI has on humanity.
The pair is part of a group of experts, known collectively as the Future of Life Institute, who recently drafted an open letter saying scientists should seek to head off risks that could wipe out mankind.
The authors said there is a 'broad consensus' that AI research is making good progress and would have a growing impact on society.
But it issued a stark warning that research into the rewards of AI had to be matched with an equal effort to avoid the potential damage it could wreak.
For instance, in the short term, it claims AI may put millions of people out of work.
