I think the computer was designed in the fashion you are explaining ,at least in a round about way. I am not to saying the human race has been reduced to machines (yet),but if you think about it just as the sub-conscious mind remembers every thing so to does your hard drive,even after you think you have erased the Operating system just type in search all and every thing you think is gone is listed. So the right brain is how you operate and the left side stores all the information,so depending on what the right brain has in mind , the left brain attempts to steer,Does this make any sense.
