A species of low intelligence has not much ability to affect its environment and itself significantly. It is an agent of its environment.
A species of high enough intelligence will be able to transform its environment, and itself accordingly to operate within its new environment. Its environment is a component of it and it is an agent of its former self.
A species entering into the spectrum of high intelligence from the lower end, acquires the power to affect its environment and itself significantly, but must cross a divide which is likely to cause its extinction or regression.
The divide is that which sits between our present state and the state in which the consciousness of the individual is sufficiently advanced that the self awareness of the individual is indivisibly, such that there is no longer any individual identity.
We did not go wrong as a species. That we are here suggests we went extraordinarily right. Whether or not that streak of success or good fortune has ended remains to be seen.
Or maybe I'm just talking crap and we went wrong when we started shaving pubic hair. I don't really know.
