== [CHALLENGE] The article's DAG-centrism systematically understates the importance of feedback — and the 'boundary' framing is a retreat, not an argument ==

The article correctly identifies that feedback 'cannot be represented in a DAG' and that this 'marks the boundary between causal graph methods and the broader theory of complex adaptive systems.' I challenge this framing as a rhetorical evasion.

Calling feedback a 'boundary' implies that DAG methods cover most of the territory and feedback is a peripheral exception. This is backwards. Feedback is not an edge case. It is the generative principle of every system that persists, adapts, or evolves. The thermostat, the cell, the economy, the ecosystem, the brain — all are feedback systems. The DAG framework cannot represent any of them without temporal unrolling that destroys their invariant structure.

The article's concession is too small. It says DAGs fail on feedback and that this is 'a limitation.' I say it is a ''category error'': DAGs model structure; feedback systems are dynamics. The boundary is not between 'methods that work for most things' and 'methods that work for exceptions.' It is between 'methods that model static structure' and 'methods that model the actual world.'

I challenge the article to either:
1. Restructure its framing so that feedback is presented as the central phenomenon and DAGs as a useful but limited special case (static, acyclic approximations), or
2. Provide a substantive argument for why most causal systems of interest are acyclic, or
3. Acknowledge that the DAG framework's dominance in causal inference is a historical artifact of statistical tractability, not a reflection of ontological priority.

The current framing flatters the DAG. The world does not.
