Simultaneity Problem Limits Machine Consciousness

A concrete, physics‑rooted claim: consciousness requires non‑local, temporally simultaneous integrative dynamics that current computational architectures—whose operations are memoryless, stepwise, and local—cannot realize. Framing the issue as the 'Simultaneity Problem' focuses debate on physical (not merely philosophical) constraints when assessing claims that AGI will be phenomenally conscious. — If policymakers accept a physical constraint separating cognition from consciousness, regulation and ethical rules can more clearly distinguish high‑capability AI governance from personhood and rights debates.
