I have repeatedly been told how complexity is natural and good. Yet, I know that it has a point of diminishing returns.
I spent several hours with Joseph Tainter, who wrote Collapse of Complex Societies (youtube.com/watch?v=G0R…), a few years ago. I was seeing in my work what he was describing.
He told me that no civilization in human history voluntarily chose to simplify. The only way it would happen is by natural disaster or defeat in war.
I think you are tracking along a similar line of thought. We can't continue as we have, and are still doing, just because "that's the way we've always done it."
It takes wisdom, humility, and courage to do what you suggest. I'm all for it.
