Inngest CTO says agent architectures have a six-month half-life
AI Engineer · youtube · 2026-07-21
Dan Farrelly argues that agent architecture has a half-life of about six months, so teams should build systems that survive the next trend rather than chase it.
- The talk revisits the recurring wave of agent patterns: RAG, ReAct, prompt chaining, orchestrator-workers, MCP, CLI, and back again.
- Farrelly’s main point is that every new trend can force a rewrite, so architecture should keep decisions closer to code and preserve flexibility.
- He focuses on the primitives that show up repeatedly in production agents and on choosing an execution layer that speeds iteration.
- The message is less about predicting the next best pattern and more about designing for change.
