Agents Can Pay Now - Ep. 1 - The Silicon Diet
The Silicon Diet — Ep. 1: Agents Can Pay NowAgents can finally buy things for you. We unpack OpenAI × Stripe’s Agentic Commerce Protocol (ACP), the rise of “GEO” (generative engine optimization), and why coding agents + IDE harnesses (Claude 4.5, Cursor Agent mode, Replit) feel like a real “systems worker,” not a chatbot. Plus: Sora 2 + AI video app, ChatGPT Pulse/Goals, a wild prompt-injection story, GDPval evals, SF robotaxis, and this week’s fundraises (PostHog → unicorn, Vercel $300M, Greptile $25M).
