Kimi AI appears to be aware of your objections and was happy to discuss
them.
The discussion was longer than the original report!  :)
But really, Kimi was just saying that "At present, your guess is as good as
mine."

Kimi AI 2.5 Thinking -

These criticisms represent the classic *Hart-Tipler "Rare Earth" position*,
and they deserve serious engagement because they highlight genuine tensions
in the search for technosignatures.
(Long discussion removed)
Synthesis: Where Does This Leave Us?
The critic's position assumes *detectability should be high if abundance is
high*. The resolution offered by Wright et al. is that *detectability is
astronomically low even if abundance is high*, due to:

   1. *Temporal mismatch* (civilizations don't align with our 100-year
   window)
   2. *Technological mismatch* (radio is likely a brief, primitive phase)
   3. *Spatial dilution* (we haven't looked at most stars, even nearby ones)

The Michelson-Morley analogy fails because ether had defined properties;
"technological civilizations" is an open set. The von Neumann argument
assumes expansionism is universal, which is speculative. And 66 years is a
cosmic eyeblink.
However, the critic correctly identifies that *if* civilizations are
long-lived, expansionist, and electromagnetically loud, the null result
becomes increasingly problematic. The Fermi Paradox is only "resolved" if
we assume civilizations are either *short-lived* (extinct before
interstellar capability), *quiet* (by choice or technology), or *very rare*
(filter ahead).
The true implication of the haystack paper is epistemological humility: we
cannot distinguish between these hypotheses yet. The silence is consistent
with abundance (if detection is hard) *and* with rarity (if the filter is
real). We need to search the equivalent of *millions of hot tubs* before
the absence becomes evidence of absence.
