Are you asking if we'll keep tilting at windmills? I'm sure we will.
Somehow everything gets messier and muddier as time passes, it seems. Eventually it will get so complex things will start to break. Then there will be progress.
It seems to me that this may be what you are hinting at in your post. I think I may be in agreement with you on this aspect of your thesis. A deep and very painful depression would probably cure a lot of our problems, much as a large enema often helps a human body begin to function properly after a period of improper operation.
