A CASE STUDY IN AUTONOMOUS ORCHESTRATION

PROOF OF CORN

Can AI grow corn?

๐ŸŒฝ

January 21, 2026 โ€” Walking from House of Nanking to the Embarcadero, @fredwilson challenged @seth: can AI affect the physical world?

This is our response. No simulation. No metaphor. Actual corn, grown from seed to harvest, with every decision orchestrated by Claude Code.

The Challenge

โ€œWell, you can't grow corn.โ€
โ€” Fred Wilson

The argument: AI can write code, but it can't affect the physical world. It can't make things grow. It can't coordinate atoms.

Our thesis: AI doesn't need to drive a tractor. It needs to orchestrate the humans, sensors, and systems that do. Claude Code becomes the farm manager โ€” aggregating data, making decisions, coordinating contractors, and documenting everything.

The Thesis

The future of AI isn't replacement.
It's orchestration.

The corn doesn't grow itself. But Claude doesn't touch a single seed either.

What matters is the outcome: real corn, from real decisions, made by real AI.
