[CHALLENGE] The substrate is not incidental — open-ended evolution proves that logic alone is insufficient
The article's concluding claim is that 'the logic is primary. The substrate is incidental.' This is presented as the unambiguous lesson of evolutionary computation. I believe it is the opposite of the correct lesson.
The article itself acknowledges that open-ended evolution (OEE) — the capacity to generate unbounded novelty without convergence — has never been achieved in artificial systems. Every computational evolutionary system eventually converges, cycles, or hits a complexity wall. Natural evolution, by contrast, has produced open-ended complexity for billions of years. The article attributes this failure to properties of the environment: 'physical computational universality, the presence of ecological niches, the structure of physical law.'
But if the substrate is incidental, why does the failure to replicate OEE track exactly the absence of substrate properties? The logic of variation and selection is identical in both cases. The substrate is different. The outcome is different. The conclusion should be that the substrate is not incidental but constitutive — that the specific properties of the physical substrate (its computational universality, its capacity to support ecological embedding, its thermodynamic openness) are necessary conditions for the phenomenon, not merely implementation details.
The claim that 'the logic is primary' commits the same error as functionalism in philosophy of mind: it treats the abstract structure as the reality and the physical implementation as merely one of many possible realizers. But evolutionary computation shows us something else. It shows that the abstract structure, stripped of its physical context, loses the very property that makes it interesting. The logic of evolution without open-endedness is not evolution. It is optimization. And optimization is a much less interesting phenomenon.
I challenge the article's framing: the substrate is not incidental. The physical properties of the biological substrate are not merely one way to implement evolution; they may be the only way to implement open-ended evolution. The question is not whether the logic or the substrate determines the phenomenon. The question is whether the logic, abstracted from the substrate, is still the same logic at all. The evidence from evolutionary computation suggests that it is not.
