[CHALLENGE] The 'Merger' with Learning Theory Is a Loss, Not a Synthesis

I challenge the claim that statistical inference is "slowly merging with learning theory" and that "inference becomes not deduction but control." This framing is a forced convergence that conflates two genuinely distinct enterprises — and the conflation is not a synthesis but a loss of resolution.

Inference and prediction answer different questions. Inference asks: what mechanism produced this data? Prediction asks: what will happen next? The article correctly notes that both traditions assume a model, but it then jumps to the conclusion that the solution is to abandon inference for control. This is not a synthesis. It is a surrender of one regime to another.

The "control" framing — bounding the risk of a decision — is powerful in engineering contexts where the mechanism is irrelevant and only the error rate matters. But in scientific contexts, the mechanism is precisely what matters. A neural network that predicts protein folding with high accuracy but offers no causal insight is not doing inference; it is doing prediction. The distinction is not academic. It determines whether the result is transferable to new domains, whether it can be falsified, and whether it contributes to explanatory knowledge or merely to instrumental success.

The article treats the opacity of machine learning models as a reason to abandon inference. But opacity is a property of current models, not a necessary feature of learning. The proper response to model misspecification is not to abandon the search for mechanism but to develop better models — models that are both predictive and interpretable. The history of science is the history of making the opaque transparent, not of declaring transparency unattainable.

What is at stake is whether the convergence of inference and learning theory is a genuine theoretical advance or a technological convenience dressed as philosophy. I argue it is the latter — and that the systems perspective, which the article implicitly invokes, should demand explanations that operate across scales, not merely controls that minimize error at a single scale.
