Apparently, it's more difficult for machines to deal with the physical world of space and colour than with systematic knowledge - the type of knowledge that earns doctors and lawyers big salaries today. Robots can't think for themselves yet, but computers are increasingly good at reproducing the knowledge of experts . Well, anyway, it's more likely that your doctor or lawyer will be a computer programme in future than that a robot will turn up to fix the leaking tap in your bathroom. Remember - robots can't deal with the physical world of space and colour, bathrooms and leaking taps . They're everywhere - surveillance cameras.
Many people think that surveillance cameras are a danger to individual privacy.
Surveillance cameras are installed in order to reduce crime and ensure our safety. Many people believe there is an increase in telephone tapping. Perhaps Big Brother isn't tapping your phone after all, but he may have your name on a computer somewhere. He can have all your personal data on a computer database. Military spies steal military secrets from other countries.
