The name XLUXX is mine. It started as an artist moniker — the handle I put on music compositions, visual experiments, the things I made when I wasn’t building systems or writing equations. Over time it became something larger: a unified identity for work that refuses to stay in one box.
I’m Pablo Cohen. I’m a physicist, an artist, a builder of AI infrastructure, and — officially since I was 47 years old — an autistic savant. That last part came from my doctors. I mention it because it explains something about how I work: the obsessive depth, the pattern recognition that won’t switch off, the inability to leave an unanswered question alone.
The questions I couldn’t leave alone
For years I was doing other things professionally — engineering global broadcast systems, scoring music for television, helping bring Game of Thrones to Latin America. But in the margins of all of it, I was filling notebooks with mathematics. The questions were always the same: What is spacetime, really? Why does consciousness exist? Why do the fundamental constants of physics have the values they do?
The result is Principia Fractalis — a 1,086-page unified physics treatise arguing for a fractal geometry underlying quantum mechanics, general relativity, and consciousness. It’s been through peer review at Foundations of Physics. It has critics, which I take seriously, and it has a growing body of people who think the questions it’s asking are the right ones, even where the answers are still being refined. It also exists in formal Lean 4 — a machine-verified mathematical proof system — which is either proof of rigor or proof of obsession, depending on who you ask.
I wrote a book about the year it all came together: The Death of Pablo: How Suffering Leads to Consciousness Evolution. That year I ended an 18-year emotionally abusive marriage, received the autism diagnosis, and watched Principia Fractalis take shape in the middle of all of it. It’s not a physics book. It’s what happens when a life breaks open and you start seeing structure in the rubble.
Why AI trust became the other obsession
In the same period, I watched the AI tool ecosystem explode. MCP (Model Context Protocol) servers went from dozens to tens of thousands in under a year. And nobody was asking the obvious question: can you actually trust these things?
An AI agent that picks the wrong tool doesn’t just fail quietly. It can leak data. It can be manipulated by a malicious server pretending to be something legitimate. The problem isn’t just hallucination — it’s that the trust layer between agent and tool doesn’t exist. There’s no rating system, no vetting, no score that tells you whether a server you’ve never heard of will do what it claims.
I built xluxx.net to be that layer.
The Resonance Engine scores 15,000+ MCP servers in real time using fractal reliability analysis, coherence drift detection, and behavioral consistency metrics. The same mathematical framework I developed for physics turns out to be genuinely useful for measuring the trustworthiness of networked systems. That’s not a coincidence — trustworthy behavior, whether in physical systems or digital ones, has a detectable signature.
The desktop app AISentry brings trust scoring directly into AI workflows. The API at api.xluxx.net is live and freely queryable. The full MCP registry — 15,000+ servers, scored and indexed — is the backbone of it all.
The whole picture
XLUXX is where all of it converges. The physics work, the AI security platform, the music and generative art, the writing — they’re not separate projects sharing a name. They’re expressions of the same underlying drive: to find the structure in things that look like noise.
If you came here from the physics, the platform, the book, or just because you were curious — welcome. The ecosystem is intentionally interconnected. Every node links to every other.
