Got it. However, unlike David Pearce, I don't think that superintelligence implies superempathy. Our particular moral concerns are essentially arbitrary, and there's no a priori reason to think they'll be preserved. (See, e.g., my and Gedusa's discussion with Arepo
here.)
It is empirically true that "the arc of history bends toward justice" (where by "justice" I mean an expanded circle of moral concern for the welfare of others), although it's hard to say how much of this is a selection effect. (The current generation always feels that it has made moral progress since generations past because it agrees more with its own values.) It does look as though human society will move toward greater consideration of animal suffering in the future. However, society is also moving toward placing more and more value on pristine wildlife. And who knows if our descendants will start becoming more passionate about
panbiotic ethics.

Well, the question is fundamentally philosophical rather than scientific. It's a judgment call about how to weight different types of brains doing emotional processing at different scales. Bentham said that "each person is to count for one and no one for more than one," but what counts as a "person"? Is it a single, autonomous agent? But in that case, what if we split your brain in half and put each half into separate bodies? Would we thereby have doubled your moral weight? (Maybe. I'm not sure.)

Same here.

True, although the less radical animal-rights activists aren't too concerned about insects. Also, I think my eventual focus might not be so much on novel research as, instead, on popularizing the abundance of high-quality animal-welfare research already published. There are hundreds of excellent papers in animal-welfare journals that barely anyone has read, and since the value of scientific research from a meme-spreading perspective is roughly proportional to the number of people who know about it, I think the largest unexploited returns could come from producing popular blogs / books / videos about what is already known.
In addition, I think there are many areas where the jigsaw pieces have been cut, but no one has put them together from a cost-effectiveness standpoint. One example is
my analysis of humane insecticides. Scientists have known all the relevant data points for decades: Insect densities on crop fields, mortality rates from pesticide application, mechanisms of pesticide action (which suggests roughly how "painful" we think they are), and costs of different pest-control methods. However, I had never before seen a calculation like mine (or, for that matter, even the idea of trying to make pesticides less painful for the target organisms, rather than just less environmentally destructive or safer for humans).
Another low-hanging fruit in terms of deriving important conclusions by just collecting a few pieces of already-known data could come from enumerating which types of environmental changes tend to produce ecosystems with lower total animal populations. For example, if we assume that the amount of animal life is roughly proportional to the amount of biomass in a given area, then we could support activities that reduce biomass. These might include
- Desertification.
- Reducing nutrient availability (e.g., limiting nitrogen and phosphorus).
- Replacing fast-growing high-turnover plants (e.g., grass and field crops) with slow-growing plants (e.g., non-tropical forests?).
- Favoring habitats with big, herbivorous animals (deer? elephants? humans?) that can consume lots of plant matter without producing lots of small creatures.
- Favoring forest and grassland fires (which, unlike animals, are a non-sentient way to convert O2 + C6H1206 -> CO2 + H2O).
- Favoring land-use changes, invasive species, genetic engineering, or geoengineering that have the above consequences.
This is another example where there's enough data to do order-of-magnitude estimates on the back of an envelope, but I don't think anyone has actually done it.
All of this said, I think winning hearts and minds -- even without any new research or analysis -- may be the most important of all, because if enough people become interested in these topics, then they can help with the research. In particular, I suspect that one of the best ways to produce useful academic output may not be to do the work oneself but to become friends with professors and graduate students who study animal welfare, ethology, entomology, neuroscience, cognitive science, philosophy, and ethics, and then spark their interest in these questions. This may be better than, say, directly studying insects in a PhD program because (1) you won't have to devote 60 hours a week to detailed lab work unrelated to science popularization and (2) you can instantaneously change focus if you discover a topic that's more important, without spending years to switch fields.
