I can't find a better place to ask this, but I was wondering whether/where there is a good explanation of the scepticism of leading rationalists about animal consciousness/moral patienthood. I am thinking in particular of Zvi and Yudkowsky. In the recent podcast with Zvi Mowshowitz on 80K, the question came up a bit, and I know he is also very sceptical of interventions for non-human animals on his blog, but I had a hard time finding a clear explanation of where this belief comes from. I really like Zvi's work, and he has been right about a lot of things I was initially on the other side of, so I would be curious to read more of his or similar people's thoughts on this. Seems like potentially a place where there is a motivation gap: non-animal welfare people have little incentive to convince me that they think the things I work on are not that useful.
