The fiercest rivals in technology just spent eighteen months agreeing to build the next internet together — Google gave away its agent-to-agent protocol, Anthropic handed the Model Context Protocol to a foundation it co-founded with OpenAI — and that act of cooperation, not any single product, is the real story of the agent era. When companies this competitive standardize a layer, it is because the layer has become a commodity and the war has moved somewhere else: to the three things they pointedly kept private — the identity that proves an agent is yours, the cryptographic mandate that authorizes it to spend your money, and the assistant that is the single front door to your life.

This is what the agentic substrate actually is, why every giant is building it at once, and why it reaches all the way into your wallet. We follow the money through A2A, MCP, Google's Agent Payments Protocol and OpenAI and Stripe's Instant Checkout to the real prize — owning the moment you decide you want something — and we ask the question the press releases skip: when software starts buying things in your name while you sleep, who is accountable, and does the front door they're building open only for you, or also for whoever learns to whisper to your agents?

I'm Dan. The AI revolution is moving way too fast for anyone to keep up — so I built a custom stack of AI tools to chase down the questions I can't stop thinking about and share what I find. These episodes started out made with NotebookLM and are now produced with my own engine; I make them mainly to learn this myself, and I publish them for anyone who'd like to listen along. AI-assisted, fact-checked, and always worth a second look.
