The battle between the ECCO faction and the SSE faction is a representation of our own, individual, biological drives and conflicts. We will certainly evolve some kind of super-powerful system and it will be an extension of biological characteristics we currently posses. The point of the idea is to realize both possibilities exist within us at this very moment and to understand our choices can influence the thing that is created that will out-pace us. It's just about which genes will be expressed into the super-system, which is the same old story since genetics begat itself.
You apparently know nothing about the typical human condition so I'm guessing you're young, had rich parents and grew up surrounded by adults who catered to your every need and smoothed out every issue that caused you negative thoughts. I suggest you read Herman Hesse's Siddhartha as an introduction to Buddhism and how The Buddha, who grew up in similar circumstances, discovered that life is suffering and how to manage this fact. Drugs, both legal and illegal, can be a tool in exploring the roots of this suffering within one's own mind.

Did Aldous Huxley take himself too seriously?
Recommended Huxley reading for the committed Materialists of HN.
