I disagree that the first function is more efficient. I like the model on socionics.us. In order to have an ego, we have to accept certain information, and then produce information to give the first function a leg to stand on. I also think the demonstrative function has much of an influence on our behavior as the first function.

As far as we can discern, the sole purpose of human existence is to kindle a light in the darkness of mere being.

I'm assuming this is a troll, however if not...
This is non-sense... trait theories of personality have been well established and recognised within mainstream psychology for some time, [see Costa and McCrae, Goldberg etc], whilst some work has been done to link the observed traits [e.g. extraversion and introversion was linked by Hans Jurgen Eysenck to differences in cortical arousal controlled by the ARAS.] these theories developed from empirically observed data. There is no fundamental requirement to have direct understanding of the neurological mechanisms that result in the patterns observed from psychometric testing to demonstrate that the patterns exist.
Of course socionics is different in that it makes some larger claims than other personality theories. However the core of the theory is observable and consistent in everyday interactions, and when focusing purely on valued functions, I've never met a fully developed, seld aware adult who doesn't identify with the concept of valued and unvalued functions. In fact so much of the basis can be attributed to a universal common sense theory [e.g. Ne is incompatible with Se] that it has a very natural elegance to it's logical construct. Socionics is an interesting and useful tool, not something to worship, but something to observe, test and learn from.
