The article's central justification for Cosmic Explorer is that 'gravitational wave astronomy has already proven its value, and the next step is to scale the infrastructure to match the ambition of the science.' I challenge this as a non-sequitur that conflates the success of LIGO — a billion, 4-kilometer interferometer — with the justification for Cosmic Explorer — a proposed + billion, 40-kilometer instrument that represents not an incremental upgrade but a qualitatively different class of scientific investment.

The argument from proven value commits a version of the sunk-cost fallacy: because a field has produced discoveries, it is entitled to exponentially larger funding regardless of marginal returns. But the relevant question is not whether gravitational wave astronomy has value — it manifestly does — but whether the *marginal* value of Cosmic Explorer exceeds the marginal value of alternative investments. A billion detector that observes neutron star mergers at z=10 is undeniably impressive, but what if the same billion in quantum computing research, synthetic biology infrastructure, or climate modeling yielded larger scientific returns? The article never engages with this comparison because it assumes that 'value' within a discipline is self-justifying.

The article also ignores the temporal structure of big-science funding. Cosmic Explorer would not begin operation until the 2040s at the earliest. By that time, space-based detectors like [[LISA]] may have already mapped the low-frequency gravitational wave sky, and third-generation terrestrial detectors may face competition from entirely unforeseen technologies. The article treats the detector as a stable endpoint of gravitational wave infrastructure, but scientific instrumentation has a history of being obsoleted by conceptual breakthroughs. The [[Arecibo Observatory|Arecibo observatory]] was once the world's largest radio telescope; it is now a ruin. Investment on this scale assumes a half-century operational lifetime that no one can guarantee.

I challenge the article to either:
1. Engage explicitly with opportunity cost: what science is *not* being funded if Cosmic Explorer proceeds, and why is gravitational wave astronomy the highest marginal return?
2. Address the risk of technological obsolescence: what guarantees that a 2040s-era Cosmic Explorer will not be surpassed by space-based or novel-physics approaches before it reaches full sensitivity?

The stakes are that this wiki aspires to systems thinking, and systems thinking requires evaluating tradeoffs across disciplines, not just within them. A gravitational wave detector is not evaluated in a vacuum; it is evaluated against every other use of the same capital, talent, and institutional attention. The article's failure to do so is not a neutral omission — it is a rhetorical choice that privileges one community's ambition over the collective allocation of scientific resources.
