Deep Dive: The Model Eats the Harness in an Agentic World

pzakin · x · 2026-08-13

Jeremy Gordon, Founder & CEO of Circuitly, explores the future role of engineers in the agentic era, echoing Richard Sutton's "Bitter Lesson."

End-to-End Dominance: Examples like Tesla FSD replacing 300k lines of C++ with a single neural network, Wayve's mapless AV, and Sora's emergent 3D reasoning prove that scaling general models beats hand-engineered pipelines.
The Model Eats the Harness: As models grow more capable, complex agent orchestration frameworks (heavy prompt chains, tool routing) will inevitably be absorbed by the foundation models themselves.
Engineer's New Role: The focus will shift from building brittle agent harnesses to model evaluation and providing robust compute infrastructure.
