Episode notes
APIs Are The Internet's Dendrites
- APIs are the fundamental connections that let software and services interact and automate workflows.
- Alex compares APIs to dendrites that enable the internet to 'think' by connecting systems.
LLMs Need Native Interfaces
- LLMs introduce a new class of actor that needs native ways to use services, not just human UIs or server APIs.
- MCP aims to be that native interface so models can perform tasks across apps directly.
Refunding A Customer Across Apps
- Alex walks through a refund workflow that spans multiple apps to illustrate the agentic AI promise.
- The example shows how one human task can require dozens of clicks across dashboards, which AI could automate end-to-end.
