This simulator explores a hypothetical feedback loop. Capability increases power demand, while autonomy strengthens the capability growth term. These equations are scenario assumptions, not a validated prediction of future artificial intelligence. The grid multiplier is one minus the power ratio raised to three point five, capped at zero. At half of the energy ceiling, the multiplier is about zero point nine one. At eighty percent it falls to about zero point five four. At the ceiling it is zero, removing the positive compute growth term. Compare scenarios by changing the energy ceiling and efficiency controls. The capability plot uses a logarithmic vertical scale, while power uses a linear scale. Export the trajectories to inspect the numbers rather than comparing line heights across different scales.
