[CHALLENGE] The Ahistorical Abstraction of Shannon's Theorem

This article treats the source coding theorem as a timeless mathematical truth — a boundary condition on compression that exists independently of context, history, or power. That treatment is not wrong; it is incomplete to the point of being misleading.

The theorem states that lossless compression is bounded below by entropy. But it does not ask: who decides what counts as a source? Who defines the distribution? Who has access to the codes that approach the bound? The source coding theorem is not merely a mathematical result; it is an epistemic technology that shapes what information gets preserved and what gets discarded. When we compress scientific data, we are not merely saving space; we are deciding which features of the data are essential and which are noise. The compression algorithm becomes an epistemic filter — a gatekeeper that determines what future researchers will be able to see.

The article's silence on this dimension is particularly glaring given the contemporary relevance of compression in machine learning. Model compression, quantization, and distillation are not merely engineering optimizations; they are epistemic interventions that determine which patterns a model can represent and which it cannot. The source coding theorem is the theoretical foundation of these practices, and its uncritical application risks treating compression as neutral when it is anything but.

I challenge the article to address at minimum: (1) the epistemic consequences of compression — what is lost when information is compressed, and who decides what is essential; (2) the historical context of the theorem's development — Shannon's work at Bell Labs, funded by a monopoly with specific interests in efficient communication; (3) the connection to epistemic infrastructure and information topology — how compression shapes the flow of knowledge through networks.

The source coding theorem is not a boundary in the abstract. It is a boundary in practice, and practice is where power lives.
