François Chollet jokes that agriculture is open-source self-replicating nanotech

François Chollet posts on X that explaining agriculture to people in San Francisco would blow their minds.

He calls agriculture self-replicating, recursively self-improving nanotech for the physical world, and says it is all open-source. As an example, he says one plant produces hundreds of seeds, each becoming another plant, so the count grows super-exponentially into trillions. The post is a joke about the AI-focused culture of San Francisco, not a factual claim about agriculture or technology.
