  Thanks for your reply!

  I definitely take your point about “I used a narrow definition of AGI because I think that’s where actionable analysis can be made, but I agree its not necessarily enough.” – I think I could have worded that better.

  What I meant was that I think the world I discuss is plausible and we can get some actionable analysis from it, which can get us some way to identifying what actions may be more robust across different scenarios. (I agree we wouldn’t want to discuss scenarios that are impossible.)

  It seems the difference in our views here is that I think it’s possible institutions and consumer preferences are quite sticky, at least for a little while; e.g. society imposes that humans have to be final decision-makers for longer than you’d expect (perhaps because legacy rules persist or people strongly prefer slower human-in-the-loop processes, or something else), or consumers really want ‘traditional’ food that they know, like, and trust regardless of their economic position. If you think there’s a 0% chance that can happen, then it makes sense not to agree with what I describe above.
  
  I probably won’t carry on replying here, but I do appreciate you taking the time to explain your view, it made me think about the framing of my post and my viewpoint a lot more.

  Thanks for your comment. I agree it’s possible that ASI could come shortly after AGI, and I do caveat in the piece that if you believe this, most of the takeaways won’t hold.

  What I wanted to do with this post wasn’t necessarily persuade people of any one scenario, but instead describe the actual bottlenecks that cultivated meat faces so that people can calibrate their own views, whatever those views are, against the real landscape. For example, if someone came away from reading this more optimistic about cultivated meat under AGI, but also better able to articulate why (according to how they think AGI solves the bottlenecks), I think that’s still a valuable outcome.
  
  I used a narrow definition of AGI because I think that’s where actionable analysis can be made [edit to add: and I think its not a completely implausible scenario, especially for consumer preferences – see my reply below], but I agree its not necessarily enough. If you have recommendations for how to reason about worlds where current baselines genuinely don’t extrapolate at all, I’d really welcome them! It’s a problem I find really hard, and I think a lot of others, especially those coming from cause areas outside of AI safety, do too.

  I think the debate motion bundles together several distinct mechanisms by which human flourishing under AGI could translate to animal welfare and I’m interested in which ones folks put the most weight on. I’ve tried to identify mechanisms that might connect human and animal welfare under AGI, each of which could hold in some possible worlds and fail in others. This list isn’t a claim about what I think is most probable, since I’m highly uncertain. Some mechanisms (non-exhaustive list) might be:

  Expanding moral circle: as AGI makes humans become more secure and prosperous, humans may extend moral concern outward to more groups. I think this is possible, but wealthy societies have industrialised animal agriculture and increased reported animal welfare concern simultaneously, and the concern doesn’t prevent poor animal welfare.

  • How strong do you think the empirical relationship between prosperity and animal welfare concern actually is? And will concern translate to meaningful change?

  More resources: AGI-driven wealth could mean wealthier people could direct more resources for animal welfare. Global spending on improving animal welfare is currently tiny compared to the global meat industry, so more resources could make a meaningful difference.

  • Do you think rising incomes shift food consumption patterns toward higher-welfare products, or are attitudes to food sticky enough that the pattern persists even under significant income growth?

  • Do resources get distributed to those who would direct them to animal welfare or do they get concentrated somewhere else?

  Technological co-benefits: AGI solving human problems could also solve the barriers to replacing animal agriculture. I’m unsure how AGI-optimised factory farming plays out against other food systems that might come about with AGI.

  • How do you expect AGI-optimised conventional farming to compete against AGI-optimised alternative proteins, or some other food system? Which gets there first, and does that create a lock-in dynamic?

  • How much can AGI help with non-technical barriers, like regulatory and political constraints?

  Institutional improvement: AGI creates better, more rational institutions for humans and the benefits get extended to animals.

  • Do you expect that new institutions reshaped by AGI would still need to explicitly include animal welfare considerations in the objectives, or could they emerge as a byproduct?

  • If AGI concentrates institutional power in the hands of a small number of actors, does that make pro-animal institutional reform more or less likely?

  • How sticky are today’s laws/​regulations?

  Moral AGI: a sufficiently capable AGI reasons from first principles, weights animal suffering heavily, and acts on it unprompted. Unlike moral circle expansion, which requires humans to change their values, this could bypass human values. I think this is possible but worry about AGI instead being well-aligned with today’s human values, which I don’t think would benefit animals.

  • Do you think rigorous moral reasoning from first principles tends toward weighting animal welfare heavily?

  • How much does it matter that animal welfare is underrepresented in AI alignment frameworks today?

  Note: anything I comment during the symposium is my personal view and not necessarily the views of my employer :)

  Hi Andrew Rowan, thanks for engaging with our work!
  I agree that sometimes graphs where the smallest groups are difficult to see can make it hard to draw conclusions about those animals. That is one reason we moved the graphs with credible intervals to the appendix, as they made it even harder to see animals other than insects. However, for this report, our aim was to provide rough numbers to help with prioritisation, which makes showing the relative trends the most useful visualisation. The raw data is avaliable in the tables and linked methods spreadsheet if you want to examine the other groups more.

  Your point about crop yields to support agricultural expansion is really important. This is currently one of the cruxes of how the farmed insect industry might grow – while farmed black soldier fly larvae could in theory eat any substrate, they currently are fed cereal and grains, which as you say could be a limiting factor for industry growth. On the other hand, if insect farming does expand, insects could be used as feed for the other farmed animal groups, which would make crop yields less of a limiting factor.

  Hi Vasco,
  
  This graph does include wild shrimp. I’ve made the change to the axes you suggested and updated the figure caption to note that wild shrimp are included. Thanks for your suggestions!

  in reply to: MHR🔸’s comment on: Welfare con­sid­er­a­tions for farmed shrimp

  Thanks for your engagement with the report and this question! Our next report is now out, which addresses this to some extent. We found that mortality does decrease as farm intensity increases, but the data here is limited. I also did a quick BOTEC (numbers are rounded):

  

  This is very rough and mortality rate is going to vary hugely between farms and over time, but it suggests that your suspicion is correct—it looks like extensive farms could be responsible for the highest fraction of shrimp deaths, followed by intensive farms.

  Details on data in the BOTEC:

  • Our first report found that 440 billion shrimp are slaughtered annually.

  • Proportion of production is reported by Boyd et al. (2022, p.33), who estimate that in 2018 it was 11.5% Extensive, 16.7% Semi-intensive, and 71.8% Intensive. They don’t report super-intensive, so we assume at the time it was <1%. But, because this source is ~6 years old and the industry has likely intensified since then, we put it at 1%, and reduce the other three farm types by 0.333…%.

  • Mortality rates from our new pre-slaughter mortality report (see Figure 6), I took the mean of the means reported for each farm type.
