What about us children masquerading as adults?
In this environment of Excess production, it's not pressing on the individual level to truly Grow-Up..
We see this with mass prevalence of irresponsibility towards not only Others (violence, uncooperativeness), but also to oneself, (obesity, sex-addiction)..
This is inherently due to the limitations of any one individual to see a larger picture than oneself, and living in excess makes it all the more murkier..
In the grand scheme, when we take a step back.. Nature is excessively dangerous despite the distance we've come.
Considering that we now know how vast and cold it is between habitable worlds.. it is not pessimism to argue, that even if we put the full resources of humanity into our science, it may still be a VERY tight race against time before demise......
it's difficult to draw motivation from an event that exists so distant from any individual's lifespan.. And so.. we've peaked in terms of the cognitive balance in our environment..
