Facebook and Google created walled gardens to profile you. AI weaponizes that data in real time — with a precision those systems never had. Jason helped build some of these ad tech systems. He knows exactly how demographic targeting worked: the pixels, the cross-site tracking, the data sharing between walled gardens. And he's clear: what AI does isn't a step further. It's multiple steps further, and fundamentally different in kind. Classic ad tech assembled your behavioral profile from discrete signals — what you clicked, what you bought, what you searched. It was good at matching you to an ad. What it couldn't do was synthesize those signals into a live model of your psychological state. AI can. The end user license agreements on every major LLM are now explicit: everything you put in belongs to the platform, regardless of what you pay. Your searches, your chats, your questions — training data. Paired with biometric inputs from wearables — heart rate variability, sleep data, stress indicators — these systems can build a real-time emotional profile that classic ad tech could only dream about. The EU has GDPR and it has teeth. Companies that don't want to pay those fines simply don't deploy certain features in European markets — they know what they're doing and they've already priced in the fines everywhere else. The US has California's CPRA, which Jason describes as lacking real teeth. Most of the world has nothing. The walled garden was always a trap. The AI-powered walled garden is a trap that reads your nervous system. 🎙️ Brobots is a weekly tech podcast hosted by Jeremy Grater and Jason Sisneros — covering AI, health, and what it means to be a better human in a world that's changing faster than the ethics can keep up. 📍 New episode every Monday → https://brobots.me 🎧 Listen on Spotify, Apple Podcasts, and everywhere else #AIPrivacy #DataPrivacy #BigTech #TechPodcast #WalledGarden
