Every morning, we lean into the day ahead without ever thinking about it. That simple move rests on a certainty we almost never question: the future doesn’t exist yet, it waits to be filled in like a blank page.

What if it were the other way around?

In my new article, I trace back an idea that makes your head spin, one that physics and philosophy have been wrestling with for a century. From Einstein’s relativity and his block universe, where past, present and future coexist, all the way to Everett’s many worlds, by way of Leibniz, Bergson and the paradox of freedom.

The time we think we live in a straight line would be a construction. Useful, impossible to shake off, but a construction all the same. Which leaves a question that neither physics nor philosophy truly settles: if every possible future already exists, what does choosing still mean?

A piece for those who lie awake over time, consciousness and free will.

Eleven players chasing a ball get universal applause. A kid who’s brilliant at math gets side-eyes. Why does France celebrate excellence in the feet and grow suspicious of excellence in the mind?

Between a football academy running on 35,000 euros per player per year and a math olympiad program held together by volunteers, the funding gap tells you exactly what kind of society we’ve chosen to be, without anyone ever saying so out loud.

On the table: the story of a single word, “elitism”, turned into the quiet weapon of a collective surrender, and the very real price France pays for being ashamed of its brightest minds.

On June 12, 2026, a single administrative letter was enough to cut off access to the world’s two most advanced AI models for millions of users outside the United States. No tanks, no missiles, just a kill switch flipped in a matter of minutes. Behind the official excuse of a “jailbreak” lies a much more mundane reality, and a far more troubling one for European digital sovereignty. In this piece, I break down the anatomy of this global shutdown: the power struggles in Washington, the murky role of industry interests, and what this “cognitive splinternet” reveals about our dependence on American artificial intelligence. An investigation that goes straight to the heart of our digital sovereignty and our ability to stand up to the tech giants.

Thales plants a stick in the ground, waits for the perfect angle of the sun, and measures the height of the Great Pyramid of Khufu without ever climbing a single step. The scene is fascinating. But it raises a question far more unsettling than the calculation itself: that morning, did he invent something, or did he simply see what was already there?

Are mathematics an invention of the human mind, or the discovery of laws that existed long before us? Newton and Leibniz developed calculus at the same time, completely independently, thousands of miles apart. The Babylonians knew the Pythagorean theorem before Pythagoras. Complex numbers, invented as a purely abstract game, turned out to be essential to quantum mechanics centuries later.

This is not a textbook question. It is a question of philosophy of mathematics, and it has no definitive answer. That is precisely why it deserves to be asked.

AI didn’t force its way in. It made itself indispensable through convenience. And we let it in, without really measuring what we were giving up in return.

In May 2026, Pope Leo XIV published Magnifica Humanitas. An encyclical about AI. Yes, you read that right. And this text says, with a clarity that most tech reports lack, what we still refuse to face: human dignity eroded by algorithms, thought that offloads its own effort, power concentrating in the hands of those who code while everyone else just absorbs the consequences.

I read this text as a practitioner, not a believer. And what I found in it mirrors exactly what I observe every day: we are no longer just automating tasks. We are delegating the way we think.

Between Babel and Jerusalem, the encyclical asks a simple, almost uncomfortable question: which construction site are we part of, right now, with the tools we use every single day? What are we actually building? And for whom?
