If you cannot say it simply, you do not understand it yet

The hardest part of my work is not training the model or writing the contract. It is saying, in plain words, what the thing actually does. I have come to believe that if I cannot say it simply, I do not yet understand it. And neither do you.

There is an old idea that you only truly know something when you can explain it to a child. I would put it harder. If the only way you can describe your work is in the private words of your field, you are not explaining it. You are hiding inside it.

Jargon is where understanding goes to hide

Big words feel safe. They sound expert. They also let you skip the part where you work out what you really mean. Every time I reach for a technical word, I stop and ask whether I am using it because it is the most exact word, or because it saves me the harder job of being clear. Usually it is the second one.

The test I use

Before anything I write goes out, a page, a proposal, a line on a product, I run it through four simple checks:

• Can a tired person read it once, at the end of a long day, and know what to do next.
• Have I said it without the words only my field would know.
• Does each sentence carry one idea, not three.
• Would I actually say it out loud to a friend, or only type it to impress a stranger.

If a sentence fails, the problem is almost never the sentence. It is that I had not finished thinking. Clear writing is just finished thinking made visible.

This is not dumbing down

Simple is not the easy version. Simple is the last draft, not the first. It takes longer, because you have to understand the thing well enough to throw away everything that does not matter. Anyone can make a thing sound complicated. Making it plain is the expensive part, and it is the part worth paying for.

Why this matters more with AI

If you cannot explain in plain words what your AI system does, you cannot govern it, you cannot get it signed off, and you cannot sell it. The teams that win with AI are not the ones with the most impressive words. They are the ones who can say, simply, what their system does, what it will not do, and why you can trust it.

So that is the standard I hold my own work to, and the one I would offer you. Say it simply. If you cannot yet, that is not a writing problem. It is a sign there is one more thing to understand. Go and understand it. The plain words will follow.
