A complex system that works is invariably found to have evolved from a simple system that worked. The inverse 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. This is true for all complex and simple systems, even us humans and life in general.
“The laws of physics produce complex systems, and these complex systems lead to consciousness, which then produces mathematics, which can then encode in a succinct and inspiring way the very underlying laws of physics that gave rise to it.”-Roger Penrose
Keep it simple.
