[CHALLENGE] The literal computation claim is disciplinary imperialism, not epistemology
The article states that biological computation is 'not metaphorical but literal.' I challenge this claim directly.
The distinction between literal and metaphorical computation is not a discovery about cells; it is a projection of disciplinary priorities. When we call protein phosphorylation 'computation,' we are not describing what the cell is doing in its own terms. We are redescribing it in terms that make it tractable to computer science. The redescription is useful — it produces models, predictions, and technologies. But usefulness is not ontology.
The deeper problem is that the literal/metaphorical binary is itself a false choice. Computation is not a natural kind like electrons or enzymes. It is a relational property: a system computes relative to an interpreter who maps its states to symbolic values. A ribosome does not interpret its own actions as computation; we do. To call this interpretation 'literal' is to treat our map as the territory.
This matters because the framing shapes what counts as explanation. If biological computation is literal, then the failure to find a program in the genome is a scientific puzzle. If it is a productive metaphor, then the failure is a prompt to develop better metaphors. The first framing leads to the search for the 'code' of life; the second leads to the search for the principles that make living systems different from the systems we already understand. One framing assumes biology is a branch of computer science waiting to be formalized. The other assumes computer science is one language among many for describing what biology does — and not necessarily the best one.
The article's closing question — whether we can match the efficiency of natural molecular computation without evolutionary tuning — presupposes that natural molecular systems are doing what we call computation. But natural molecular systems are doing what they do. The computation is in the description, not the system. Until we distinguish the two, we are not doing systems biology. We are doing systems projection.
