You use AI every day. Not Siri, not ChatGPT — your brain.
We learn in school that our number system is based on ten fingers, and that's true. But there's much more to it. Your head doesn't just calculate — it recognizes patterns, estimates probabilities, and operates with a kind of internal language model: You sense which word fits with which, before you've finished thinking the sentence. You know intuitively that "Good" is probably followed by "morning" and not "mailbox." Your brain constantly completes, predicts, combines — with an accuracy that's astonishing.
That's exactly what modern AI does too. Just differently.
ON and OFF — the foundation of everything
The computer has no sense of language. It has no ten fingers. It doesn't even have two. What it has are exactly two states: ON and OFF. Current flows — or current doesn't flow. 1 or 0.
It sounds absurd, but from these two states emerges everything you see on a screen. Every photo, every search filter, every listing on a portal like CaravanDrive — ultimately just ON and OFF, millions of times and lightning-fast in sequence.
Draw four circles next to each other on a sheet and write underneath: 8 — 4 — 2 — 1. Each position is worth twice as much as the one to its right. Each circle is a switch — ON or OFF. Now you can build any number from 0 to 15:
A 3? Switch 2 ON, switch 1 ON — switch 4 OFF, switch 8 OFF.
A 7? Switch 4 ON, switch 2 ON, switch 1 ON — switch 8 OFF.
A 10? Switch 8 ON, switch 2 ON — switch 4 OFF, switch 1 OFF.
With four switches: 16 numbers. Double to eight switches and you get 256 — exactly the number that will reappear when we talk about screen colours. With 32 switches: over four billion. That's exactly how every computer, smartphone, and server in the world works.
How switches become a motorhome
Imagine you're sitting at the kitchen table and opening CaravanDrive. You see the photo of a motorhome on a meadow in Bavaria. Between the server in a German data center and your eyes lies a journey that happens almost at the speed of light.
Your screen consists of around two million tiny points — pixels. Each pixel lights up in three primary colors: red, green, and blue. The brightness of each color is a number between 0 and 255 — exactly eight switches, eight times ON or OFF. A single pixel therefore needs 24 switch positions for its color.
On the server, the photo exists as a file of zeros and ones. It's broken into packets and sent through the internet — via fiber optic cables, where the data travels as flashes of light. Light on: 1. Light off: 0. Almost at the speed of light. Across Germany in just a few milliseconds.
At your home, your computer reassembles the packets, the graphics card calculates a color instruction from each number, and millions of tiny LEDs light up exactly as bright as their number dictates.
You don't see the motorhome. You see points of light, so cleverly arranged that your brain — your very personal AI — makes a motorhome out of them.
Two levers
Everything you've just read is the foundation. The zeros and ones. But how does this become an entire portal — with listings, search filters, dealer backend, automatic image processing, trilingual content, a blog, an intelligent help system, and vehicle wikis for hundreds of models?
In the past, you needed a team for this. An agency. A six-figure budget. Today it takes two levers.
The systems thinker
I've been developing websites for decades and have witnessed the entire evolution of the internet — from the first HTML pages to today's complex applications. I think in systems: How do database, server, user interface, and business logic connect? What does the user need? Where do problems arise before they become visible? This thinking cannot be replaced — not by technology, not by AI. It's the foundation on which everything builds.
Claude — the AI
The second lever is Claude — an AI from Anthropic. Claude isn't a tool I use, and not an assistant I dictate tasks to. We work together like two developers at the same desk. I describe an idea, Claude knows the entire codebase of the project — every file, every function, every dependency — and together we develop the solution.
We plan architectures, discuss approaches, conduct security audits. In a single audit, we jointly identified and cleaned up 232 files and around 29,000 lines of dead code across three portals — systematically, file by file, without breaking anything. If Claude sees a better way, he says so. If I want a different direction, he implements it and explains why he would do it differently anyway.
CaravanDrive wasn't created from a blueprint and isn't based on any purchased template, page builder, or ready-made marketplace plugin. Every line of code is written for exactly its purpose. And it's far from the only portal — in total, six portals have been built from scratch this way. Each one custom-tailored.
Where the AI is embedded — and why you don't notice
The special thing: Claude isn't just part of CaravanDrive's development. He's also in the product itself. And so invisibly that you as a user would never notice.
All of this runs in the background. The user only sees the result: a portal that feels like a large team is behind it.
Are you reading this article in English or Dutch right now? Then Claude translated it. The German original text you're reading here was written by me — the other language versions were created by the AI that helped build this portal. You're experiencing exactly what this article is about.
Aladdin and the magic lamp
Do you know the story of Aladdin? He finds an old, unremarkable oil lamp. No one would suspect anything special about it. But he rubs it — and a genie appears who makes his wishes come true.
Sometimes I sit in the evening in front of my screen and look at what we've accomplished in a single day. A new feature, a solved bug, an entire wiki system for hundreds of vehicle models. And then I think of the old lamp.
My terminal looks like that lamp. Black background, blinking cursor, nothing impressive at first glance. But when you know how to ask, something emerges from it that no human could have imagined half a century ago.
A seller in Bavaria photographs his motorhome. The camera converts the light into millions of zeros and ones. These zeros and ones travel as flashes of light through fiber optics across the country, land on a server, are optimized into four image sizes, linked with an automatically generated wiki article, made accessible in three languages — and appear as points of light on a kitchen table in Emsland.
The light that was once reflected from the meadow in Bavaria is recreated on your screen. Pixel by pixel. Switch by switch.
It all began with the simplest idea anyone ever had: Two states. ON and OFF. That's all you need — if you know what you want to make from it. A systems thinker, an AI, and a magic lamp with a blinking cursor. This is how zeros and ones become a portal that transports a motorhome from a Bavarian meadow to a kitchen in Emsland — point of light by point of light, switch by switch.
