The current form of the Seidel–Bostrom Event Horizon Bound (SBEB, Seidel 2025b; DOI:10.5281/zenodo.17505947) demonstrates that the physical realization of polynomial-timeNP interventions inevitably leads, beyond a specific threshold, to the formation of an eventhorizon that causally isolates the computation. This paper derives a direct consequencefor Artificial General Intelligence (AGI) and Artificial Superintelligence (ASI): Even indistributed architectures, the coherence and synchronization required for global computationenforce an effective localization of energy within the causal diamond of the final reduction.Once the Schwarzschild condition is satisfied, an event horizon forms and isolates thecomputation. Therefore, AGI/ASI systems are not indefinitely scalable; gravitation imposesa hard, system-specific upper limit on computational growth. We formulate the assumptions,sketch the derivation (local density condition, causal volumes, synchronization energy), anddiscuss implications for both real and simulated universes.
