Between the Ears

In the human body there are 2 ears.The most sensitive of the organs lie in between the 2 ears.these organs are the sole reason the human body has become so dependent on the greatest(most useless) invention of mankind ,the computer.
now, talking in technical terms we can find out the reason for our dependence on this machine.A human cant beat a computer in a game of chess.this despite the fact that the human brain is blessed with infinite cache levels, processing rate superior to the fastest supercomputer.
It is the utilisation of these resources that is of paramount importance.Every body knows that we use only a portion of our brain.but seldom has anyone thought, why?
below is one theory that I think may be good enough.
The eyes are our 'stdin' and the brain the processor.When the mode of input is not efficient, the processor doesn't get to do too much work.
Our eyes fill the input buffer in the form of uncompressed images.Even when the only input required is text,or symbols encoded into various formats so that the processor time is not wasted.
This is why we are able to use only a fraction of its capacity. To perform calculations we need only the inputs, not the data in the form of pixels.The fact that we are able to pick data from such a large number of pixels(ideally infinite),in nanoseconds(perhaps even less) proves that our brain has much more capacity than the best of the supercomputers.
Meditation improves this quality of the brain to concentrate on the input symbols rather than the data in the form of pixels.
This is just my theory on why our brain doesn't work as much as it can.I haven't started meditating yet,So there might be a few glitches which have been introduced in the translation from pixels to symbols.

Please point these out.
