How to oppose the flexible personality structure

All the lectures and discussions this semester have revolved around the age we live in of networks replacing hierarchies, searchable databases replacing linear narrative, fixed, primary personalities being replaced by open ended, mutable, self-constructed personalities. This all points to a history of human “progress” as a slow dissolution into greater and greater societal, informational and personal, entropy. As information proliferates all things become less meaningful.
Our identities are being sold to us as ours to mold from the myriad of options out there, but what is really happening is that things are becoming more homogenized and less meaningful. This will eventually result in a loss of identity, a mass consciousness, uploaded, wired in, easily monitored, predicted and controlled.
The only way to fight this trend is to return to a view of core, immutable personality. Because the world is only familiar with this kind of view through the lens of thinkers like Nietzsche and Ayn Rand, who present a heroic, self-congratulatory, selfish, morally despicable view of core personality and will, the idea of a strong, in-born personality is frightening to most. I am confident that there is a way to be who you have been since birth without being self-serving and dangerous to others. Get your ego out of the way to be what you were made to be, whether “you” like it or not. Ego is a virus in the system. Self is what we were originally programmed to be. I want to see individuality gained through submission to the Self, rather than through an imposition of the Ego on to the Self. I suspect that if this were to happen, and we all began playing the roles we were intended for, we would begin organizing our world and information in an anti-entropic way. The question then becomes, what is the anti-Ego-virus program that we need to run in order to right things?
