I realize this view sounds outlandish to most but it’s a considered, researched conclusion.
There’s lots of evidence of insentience in the way animals behave. If they were sentient, they would not behave the way they do: https://blog.dennishackethal.com/posts/evidence-of-animal-insentience

In the reasoning you link in support of animal insentience, you argue that similarities between human and animal nervous systems do not tell us whether the same conscious “software” is running. But humans and other mammals are not analogous to two identical computers on which entirely unrelated programs happen to have been installed. The relevant systems have a shared evolutionary history, with substantial continuity in sensory, affective, nociceptive and learning mechanisms.
A change in that inherited system may indeed have produced the qualitative leap to universal creativity. Since universality is necessarily all-or-nothing in the relevant sense, that leap is unsurprising. But it does not follow that every other aspect of mental life (including pain or other phenomenal experience) must have appeared in the same leap, or even require a comparable leap at all.
Neural continuity therefore seems evidentially relevant even if it cannot by itself prove sentience. The observation that universal creativity is uniquely human still leaves open whether older, shared systems already supported phenomenal experience.
Neural continuity therefore seems evidentially relevant even if it cannot by itself prove sentience.
No, the substrate independence of computation rules that out. Neurons don’t matter for our purposes here, at all.
I agree of course that consciousness, if computational, need not depend on neurons as a particular material substrate. But that is different from saying that the organization and activity implemented by those neurons tell us nothing.
The article you link makes this distinction itself: substrate independence means that most details of the substrate do not matter; what matters is the relevant pattern or structure of information processing. Studying homologous neural systems can give us evidence about exactly that organization and processing.
So my claim is not “they have similar neurons, therefore they have similar experiences.” It is that there is evolutionary continuity not only in the neural substrate, but also in how systems involved in sensory, nociceptive and affective processing are organized, what signals they process, and how they interact with other systems.
That seems evidentially relevant to what information processing is occurring. Substrate independence does not make that evidence irrelevant.
