Before I started building companies, I was at a private school in Zürich, specialising in artificial intelligence and in finance and banking.

I have been building software with AI agents for two years — since before that was how anyone worked. Before that I was building platforms too, and working in art platforms.

Today I am building PP15.ONE, a marketplace where you can buy, sell and create digital land about anything and everything — a sport event, a music event, a festival, whatever people care about.

The essay below began as a note about one file in that repository. It became forty pages.

Building

PP15.ONE

Digital land

I started PP15.ONE about a year and a half ago, and it is now at the point where it can launch.

I built it because the idea keeps holding my attention: on this platform anyone can genuinely take part — in everything and anything.

The Unverifiable Decade

Machines We Cannot Check

Software has stopped being able to tell the difference between I checked and found nothing and I did not check. Both are reported as success.

A file in my repository reported a passing test from the first commit and never examined anything. Its entire contents were the text of an error message. Run alone, the test runner counted it as a pass. Run by the project’s own command, it did not appear at all.

The essay traces that shape through four levels: one file, one test command, a census commissioned to measure the problem and blind in the same way, and the evaluations that decide whether an AI model is released. It ends with two bets, each with a date and a probability I am willing to be wrong about.

Seven chapters and a full evidence section. Every commit hash, timestamp and console output is reproducible from the repository it describes, and every source carries one of three labels: read, quoted, or unverified.
