If we are engineered, we've been put into the contraint of
our brain setup as well as into the constraint of our bodies. Human brains, although different, are very similar indeed. The whole process of thinking and the thoughts we develop puts us into a virtual "cage" of neuron interactivity principles inside our skulls... By that I mean that we all only have one similar mechanism of looking into this world: through the inter-exchange of neuron signals - analysis of the signals from the outer. Then something that is "US" somehow picks it up from the neuron exchange. It means that whoever we are, we are dependent on a fairly smart, but still limited and time to time faulty "computer". DULL, EY!!! Does it mean we are limited on purpose and do we want to be limited, whatever that purpose is... Or may be some of us will question the idea of "engineering"???
