Simple vs Easy
Simple is not the same as easy.
There are things that are easy to implement but create dependencies (complex) versus things that might be harder initially but stand alone (simple).
Simple comes from Latin simplex: "one fold" or "one twist."
The opposite of simple is complex. Complectere: "to braid together." When something is complex, you can't understand one part without understanding the others. They're tangled together like headphone cables in your pocket.
Easy comes from Latin adjacens: "to lie near." Something is easy when it's close to us. Physically at hand. Familiar to our experience. Within our current capabilities.
The opposite of easy isn't "difficult." It's "hard."
Difficult comes from Latin difficilis: dis- ("not") + facilis ("easy"). So "difficult" just means "not easy" - it's about the gap between our abilities and what's required.
Hard comes from Old English hearde, meaning "firmly" or "severely." Hard is an inherent property. The thing itself is resistant or strong.
A rock is hard. A math problem is difficult for some, easy for others.
When you're building something - a program, a business, or a country - go hard and simple, not easy and complex.
The original internet was hard but simple. Today it's mostly easy but complex.
