Gall’s Law

A complex system that works is invariably found to have evolved from a simple system that worked. The inverse proposition also appears to be true: a complex system designed from scratch never works and cannot be made to work. You have to start over, beginning with a simple system.

Gall’s Law states that all complex systems that work evolved from simpler systems.
If you want to build a complex system that works, build a simpler system first, and then improve it over time.
