    #185 – Lewis Bollard on the 7 most promising ways to end factory farming, and whether AI is going to be good or bad for animals

    #185 – Lewis Bollard on the 7 most promising ways to end factory farming, and whether AI is going to be good or bad for animals

    "The constraint right now on factory farming is how far can you push the biology of these animals? But AI could remove that constraint. It could say, 'Actually, we can push them further in these ways and these ways, and they still stay alive. And we’ve modelled out every possibility and we’ve found that it works.' I think another possibility, which I don’t understand as well, is that AI could lock in current moral values. And I think in particular there’s a risk that if AI is learning from what we do as humans today, the lesson it’s going to learn is that it’s OK to tolerate mass cruelty, so long as it occurs behind closed doors. I think there’s a risk that if it learns that, then it perpetuates that value, and perhaps slows human moral progress on this issue." —Lewis Bollard
    In today’s episode, host Luisa Rodriguez speaks to Lewis Bollard — director of the Farm Animal Welfare programme at Open Philanthropy — about the promising progress and future interventions to end the worst factory farming practices still around today.

    #184 – Zvi Mowshowitz on sleeping on sleeper agents, and the biggest AI updates since ChatGPT

    Many of you will have heard of Zvi Mowshowitz as a superhuman information-absorbing-and-processing machine — which he definitely is. As the author of the Substack Don’t Worry About the Vase, Zvi has spent as much time as literally anyone in the world over the last two years tracking in detail how the explosion of AI has been playing out — and he has strong opinions about almost every aspect of it.

    AI governance and policy (Article)

    AI governance and policy (Article)

    Today’s release is a reading of our career review of AI governance and policy, written and narrated by Cody Fenwick.
    Advanced AI systems could have massive impacts on humanity and potentially pose global catastrophic risks, and there are opportunities in the broad field of AI governance to positively shape how society responds to and prepares for the challenges posed by the technology.
    Given the high stakes, pursuing this career path could be many people’s highest-impact option. But they should be very careful not to accidentally exacerbate the threats rather than mitigate them.
    If you want to check out the links, footnotes and figures in today’s article, you can find those here.

    #183 – Spencer Greenberg on causation without correlation, money and happiness, lightgassing, hype vs value, and more

    "When a friend comes to me with a decision, and they want my thoughts on it, very rarely am I trying to give them a really specific answer, like, 'I solved your problem.' What I’m trying to do often is give them other ways of thinking about what they’re doing, or giving different framings. A classic example of this would be someone who’s been working on a project for a long time and they feel really trapped by it. And someone says, 'Let’s suppose you currently weren’t working on the project, but you could join it. And if you joined, it would be exactly the state it is now. Would you join?' And they’d be like, 'Hell no!' It’s a reframe. It doesn’t mean you definitely shouldn’t join, but it’s a reframe that gives you a new way of looking at it." —Spencer Greenberg
    In today’s episode, host Rob Wiblin speaks for a fourth time with listener favourite Spencer Greenberg — serial entrepreneur and host of the Clearer Thinking podcast — about a grab-bag of topics that Spencer has explored since his last appearance on the show a year ago.

    #182 – Bob Fischer on comparing the welfare of humans, chickens, pigs, octopuses, bees, and more

    #182 – Bob Fischer on comparing the welfare of humans, chickens, pigs, octopuses, bees, and more

    "[One] thing is just to spend time thinking about the kinds of things animals can do and what their lives are like. Just how hard a chicken will work to get to a nest box before she lays an egg, the amount of labour she’s willing to go through to do that, to think about how important that is to her. And to realise that we can quantify that, and see how much they care, or to see that they get stressed out when fellow chickens are threatened and that they seem to have some sympathy for conspecifics.
    "Those kinds of things make me say there is something in there that is recognisable to me as another individual, with desires and preferences and a vantage point on the world, who wants things to go a certain way and is frustrated and upset when they don’t. And recognising the individuality, the perspective of nonhuman animals, for me, really challenges my tendency to not take them as seriously as I think I ought to, all things considered." — Bob Fischer
    In today’s episode, host Luisa Rodriguez speaks to Bob Fischer — senior research manager at Rethink Priorities and the director of the Society for the Study of Ethics and Animals — about Rethink Priorities’s Moral Weight Project.
    Links to learn more, summary, and full transcript.
    They cover:
    The methods used to assess the welfare ranges and capacities for pleasure and pain of chickens, pigs, octopuses, bees, and other animals — and the limitations of that approach.Concrete examples of how someone might use the estimated moral weights to compare the benefits of animal vs human interventions.The results that most surprised Bob.Why the team used a hedonic theory of welfare to inform the project, and what non-hedonic theories of welfare might bring to the table.Thought experiments like Tortured Tim that test different philosophical assumptions about welfare.Confronting our own biases when estimating animal mental capacities and moral worth.The limitations of using neuron counts as a proxy for moral weights.How different types of risk aversion, like avoiding worst-case scenarios, could impact cause prioritisation.And plenty more.Chapters:

    #181 – Laura Deming on the science that could keep us healthy in our 80s and beyond

    "The question I care about is: What do I want to do? Like, when I'm 80, how strong do I want to be? OK, and then if I want to be that strong, how well do my muscles have to work? OK, and then if that's true, what would they have to look like at the cellular level for that to be true? Then what do we have to do to make that happen? In my head, it's much more about agency and what choice do I have over my health. And even if I live the same number of years, can I live as an 80-year-old running every day happily with my grandkids?" — Laura Deming
    In today’s episode, host Luisa Rodriguez speaks to Laura Deming — founder of The Longevity Fund — about the challenge of ending ageing.
    Links to learn more, summary, and full transcript.
    They cover:
    How lifespan is surprisingly easy to manipulate in animals, which suggests human longevity could be increased too.Why we irrationally accept age-related health decline as inevitable.The engineering mindset Laura takes to solving the problem of ageing.Laura’s thoughts on how ending ageing is primarily a social challenge, not a scientific one.The recent exciting regulatory breakthrough for an anti-ageing drug for dogs.Laura’s vision for how increased longevity could positively transform society by giving humans agency over when and how they age.Why this decade may be the most important decade ever for making progress on anti-ageing research.The beauty and fascination of biology, which makes it such a compelling field to work in.And plenty more.Chapters:
    The case for ending ageing (00:04:00)What might the world look like if this all goes well? (00:21:57)Reasons not to work on ageing research (00:27:25)Things that make mice live longer (00:44:12)Parabiosis, changing the brain, and organ replacement can increase lifespan (00:54:25)Big wins the field of ageing research (01:11:40)Talent shortages and other bottlenecks for ageing research (01:17:36)Producer and editor: Keiran HarrisAudio Engineering Lead: Ben CordellTechnical editing: Simon Monsour and Milo McGuireAdditional content editing: Katy Moore and Luisa RodriguezTranscriptions: Katy Moore

Essential listening for all

Delightful podcast - very educational for anyone interested in the world, not just people interested in effective altruism. The hosts are incredibly well prepared and have a lot to add to the conversation without making it about them. While the long (many hour) nature of the conversations allows you to really get a deep understanding of the guests views, something that is rare for interviewees of this caliber.

Always thoughtful discussions with experts in unexpected fields

This podcast does a great job at taking complex topics and breaking them down into understandable concepts - all without dumbing it down for its audience. Without getting caught up in the typical conversations/debates dominating the news cycle, Rob and his guests discuss some of the most pressing issues facing the world (and adding in Some good career tips for anyone in that phase of life). Also love their afterhours sister podcast for extra content.
