Most people fear Claude Mythos. I fear Meta
They just dropped TRIBE v2. A digital twin of your brain. I used to think AI risks were just about bad code. Rogue models. Misaligned chatbots. Then I read the Algonauts 2025 results. And my whole mental model of what "AI danger" actually means just broke. We worry about AI breaching our servers. The real danger is algorithms mapping our biology. Meta trained this thing on 1,000 hours of fMRI scans from 700 real people. It maps 70,000 brain regions. Blood flow. Oxygen levels. Neural activity. All to predict exactly how you will react to a video, a sound, a single word. It does not read your thoughts. It does something worse. It predicts your dopamine hits before you even feel them. Sit with that for a second. If an algorithm knows exactly what triggers you... what image, what word, what sound hits your reward system... it does not need to guess anymore. It rehearses on a copy of your brain first. Then it builds the perfect trap. And you never see it coming because the trap was designed around you specifically. Meta did not even keep this locked up. They open sourced the whole thing. Code, weights, everything. Handed it to the entire world. This is the same company that got caught making Instagram actively harm teenage girls. The same company whose own internal research showed their algorithm pushes rage because rage keeps you scrolling. That company now has a working map of how your brain responds to everything you see and hear. They do not have to guess what keeps you glued to the screen anymore. They already know. They rehearsed it on a copy of you before you ever saw it. The product was never the app. The product was always you. Save this. Come back to it later. Because by the time most people understand what just dropped, it will already be running inside every platform they use every day.
