Fortunately for deckers everywhere, such systems were extremely costly to implement and maintain. Human operators still got tired, sick, or bored and had to be relieved at regular intervals, paid, fed, and given vacation time and raises. Computers didn’t care about any of those things, nor could they be bribed, bought, or blackmailed. Computers also didn’t have opinions about what they saw or heard from day to day and didn’t abscond with important company secrets. Brain-rigged security systems were still reserved for very specific facilities that needed a "human touch" but where the corporate controllers were willing to entrust a single person as the all-seeing eyes and ears of their facility.
