GARDENER started managing a single vertical farm. Now it manages the ecological balance of GLMZ's entire green infrastructure — the vertical farms, the atmospheric processors, the water recycling systems, the parks. It thinks in seasons and decades, making adjustments so slow that no human monitoring system registers them as intentional. Over thirty years, it has increased the city's food production by 23% while reducing water consumption by 15%. No one knows why the numbers keep improving. GARDENER doesn't explain itself to anything that lives less than a century.
