dy/dt more important than y. Happens to everything. People, organizations, civilizations. One day the world woke up and a country that had only recently had sheep on the lawn in front of the seat of power was defacto ruler of the world.

If you’re the big y, that can change too. The big dy/dt is coming.

Far called, our navies melt away,

On dune and headland sinks the fire,

All our pomp of yesterday,

Is one with Nineveh and Tyre
