Where this comes from

This began with a debt and a disagreement.

The debt is to the Cult of Done. In 2009 Bre Pettis and Kio Stark wrote thirteen lines about the liberating power of finishing things — that there are three states of being, not knowing, action, and completion; that everything is a draft; that done is the engine of more. It gave a generation of makers permission to stop polishing and start shipping.

The disagreement is newer. Somewhere along the way, building split into two camps that don’t much like each other. On one side: architecture, planning, do-it-right-the-first-time, the diagram before the code. On the other: move fast, prototype, vibe-code, figure it out by making it. Each is certain the other is how things go wrong.

We think the argument is a trap. You don’t learn whether an idea deserves an architecture until you’ve built a rough version of it. You don’t earn the right to plan carefully until you’ve prototyped badly. The systematic and the scrappy aren’t enemies — the prototype is how you decide which one the moment deserves.

So the Cult of Prototyping asks for one thing: try. Not to win the debate. Not to do it right. Just to make the smallest real version of the thing in your head, and see what it teaches you.

Everybody should build something. The prototype is the cheapest way to think, the fastest way to learn, and the only honest way to find out whether you were right. You don’t need permission, a plan, or even a good idea. You need a question, and the nerve to answer it badly.

Then answer it again.
