If you read this blog at all, all of this will sound familiar.
I like to call the concept of this barrier Plato's Desktop - like Plato's Cave, only networked.
Networked is a key piece not covered in this article; we might like to think we're independent silos, but we're not. There's a fourth leg, a fourth dimension to that stool of our lives - and that's society.
The more we deny this fact and try to act as though we're not connected, the greater becomes the friction between us - witness politics on both sides of the border or the increasing tensions between the 1% and everyone else.
We're chafing against the glass walls of our own perceived limitations and will continue to do so until we break through.
That part is inevitable; it's the wait while pressure builds that is enough to drive one crazy.
