The internet is shifting from pages humans visit to resources agents use

Greg Isenberg's core thesis is that the internet is shifting from pages that humans visit to resources that agents use — and he doesn't think that's a crazy claim. The best opportunities look really small right now because the agent internet is still small relative to where it's going. But that's how the biggest businesses always start. Building in this era — 2026, 2027 — is like building an app when the App Store launched in 2009. When you see Cloudflare talking about AI crawlers, X402, paid access, MCP tools, and monetization, don't dismiss it as a niche publisher story. Agents are becoming buyers, websites are becoming resources, and the next great internet businesses might be tiny paid doors that agents walk through all day — doors that you own as an asset.
