A Song of Types and Agents - Roberto Stagi, Ratel
Takeaway
TypeScript is a practical agent-building language when shared application types and ecosystem integration matter most.
Summary
- The talk locates TypeScript's AI growth in the application layer while reserving a major role for Python in training, research, and GPU serving.
- One TypeScript codebase can contain UI, backend, agent loops, and tools, reducing cross-language service contracts.
- Shared Zod schemas keep data contracts consistent across model interactions and frontend components.
- The npm ecosystem and growing AI tooling, including the Vercel AI SDK, make it easier to integrate agents with authentication, payments, and existing applications.

Original description
Python ruled unchallenged for a decade, sitting comfortably on the AIron Throne. But a quiet rebellion is brewing: the entire stack that actually deploys AI agents in production runs on npm, not pip. This lightning talk is an opinionated, slightly unhinged tour of how TypeScript is taking over the AI throne, why this happened and how you can prepare for it. Speakers: Roberto Stagi (Ratel): Roberto is the CTO & Co-Founder of Ratel, context layer for AI Agents, EU-Ambassador at AI Socratic, and deep into the mission of making context engineering simple for everyone.
