So, it is my personal perspective that we are running up against the limits of the human brain. We evolved for a very different life circumstance and we are failing to intellectually keep up with the perspectives applicable to today.
This is an interesting perspective that I don't think that I've heard before in this context. I tend to think of the attitudes that you mention (studiously ignoring the politics!) as a matter of degree, not kind. By which I mean that we've had similar external issues repeatedly in the past: the inventions of movable type, photography, motion pictures, radio, television, Industrial Revolution, toasters, automobiles &c... In each step of progress there are people who may refuse to address the advancement, as well as people who will make use of it without having a clue as to how the particular thing works. For instance, I could never reproduce the computer that I'm typing on, but I'm happy to use it. Then there are others who refuse to even use a computer, or a cell phone, or what have you.
So is the issue that technology has advanced beyond our biological capability to incorporate it into our understanding of the world? Or is it lack of tolerance by institutions that are threatened by it? Consider the widespread history of the church torturing and killing innovative thinkers, or thousands of years of various instances of and manifestations of political corruption.
The latter two are problems that the Epicureans have addressed in various ways from their beginning. Perhaps examining this can bring some hope that we may have tools to address the current state of affairs.
As Don mentioned in another thread, could theories of extended cognition be useful in this regard as well?
