What if robots decide they want to take control?

Speaking at the University of Oxford last May at the annual Silicon Valley comes to Oxford event, Bostrom said: "I personally believe that once human equivalence is reached, it will not be long before machines become superintelligent after that. It might take a long time to get to human level but I think the step from there to superintelligence might be very quick. I think these machines with superintelligence might be extremely powerful, for the same basic reasons that we humans are very powerful relative to other animals on this planet. It's not because our muscles are stronger or our teeth are sharper, it's because our brains are better."
