Most experts mistake complexity for depth. The translation hasn’t happened yet.
The real test: explain it to someone outside the domain, without jargon or assumed knowledge. If you can, you understand it. If you can’t, you’ve learned the vocabulary, not the thing itself.
Explaining what money does came easily. Explaining what it is took years. Everyone uses price. Almost no one defines it. It’s not a value. It’s a ratio: the value of one asset expressed relative to another, at a specific moment in time. That sentence took years to simplify.
Simplification is not a courtesy to the audience. It is a diagnostic for the speaker.
The complex version is always the first version. The simple version survives rigorous thinking.
