Eyes are sensors too. They've just been historically better than man made sensors. At some point we'll be able to collect enough data using man made sensors and then turn it into a clear enough picture using computers that the benefit of having a human making decisions will be limited at best. It doesn't even have to be as good as a human could be; it just has to be good enough given the problem space and the economic forces involved.
