A complex system that works is invariably found to have evovled from a simple system that worked. A complex system designed from scratch never works and cannot be patched up to make it work. You have to start over with a simple system.

You are never dedicated to something you have complete confidence in. No one is fanatically shouting that the sun is going to rise tomorrow. They know it's going to rise tomorrow. When people are fanatically dedicated to political or religious faiths or any other kinds of dogmas or goals, it's always because these dogmas or goals are in doubt.
