I don’t think it’s necessary to do the math with nonhuman animals in the post. You could just mention the considerations I make and that you would use different numbers and get different results for animal work. I suppose there could also be higher leverage human-targeting neartermist work than ETG for GiveWell-recommendes charities, too, and that could be worth mentioning. The fact that extinction risk reduction could be bad in the nearterm because of its impacts on nonhuman animals is a separate consideration from just other neartermist work being better.
On 2, I don’t think I’ve seen any formal writeup anywhere. I think Carl Shulman made this or a similar point in a comment somewhere, but it wasn’t fleshed out in the comment, and I’m not sure that what I wrote is what he actually had in mind.
