I learned Gall's Law while reading it:
"A complex system that works is invariably found to have evolved 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 working simple system."
That‘s also one of the reasons why socialism or centrally planned economy cannot work.
