A CASE STUDY

Can AI grow corn?

On January 21, 2026, @fredwilson challenged @seth: AI can write code,
but it can't affect the physical world.

This is our response. Real corn, grown from seed to harvest, with
every decision made by Claude Code.

The Thesis

AI doesn't need to drive a tractor. It needs to orchestrate the
systems and people who do.

A farm manager doesn't personally plant every seed. They aggregate
data, make decisions, coordinate contractors. Claude Code becomes
that farm manager-- 24/7, data-driven, fully documented.

The Architecture

+-------------------------------------------------+
|              CLAUDE CODE (Brain)                |
|  * Aggregates sensor data + weather forecasts   |
|  * Makes planting, irrigation, harvest decisions|
|  * Coordinates human operators                  |
+-------------------------------------------------+
