  • 17 - Caspar Oesterheld on evidential cooperation in large worlds (ECL)
    Aug 3 2025
    In this episode, I chat with Caspar Oesterheld about a relatively simple application of weird decision theory: evidential cooperation in large worlds, or ECL for short. The tl;dr is you think there's at least some small probability of a very large multiverse, so you try to follow something closer to the average of all the values of civilizations in that multiverse that think like you, and therefore 'make it more likely' (in an evidential way) that those other civilizations do things that you like. Links for various things that Caspar has provided: ECL overview page: https://longtermrisk.org/ecl A while after the recording, Caspar and others started this ECL-related fundraiser: https://manifund.org/projects/acausal-safety-fund-a-team-to-do-research-and-interventions Yudkowsky: Timeless Decision Theory. https://intelligence.org/files/TDT.pdf Functional Decision Theory is introduced in the following two papers.

  • 16 - Alessandro on learning Latin and Greek
    Jun 30 2025

    In this episode, I chat with Alessandro (@polisisti on X/Twitter) about our respective experiences learning Latin (and in his case ancient Greek).

    The Ranieri-Roberts approach to learning ancient Greek: https://www.youtube.com/watch?v=2vwb1wVzPec

    We need to talk about Latinitas: https://foundinantiquity.com/2024/04/15/we-need-to-talk-about-latinitas/

    Legentibus: https://legentibus.com/

    Intermediate-level Greek texts:

    There is a good series called "Reading Greek" published by the Joint Association of Classics Teachers. An example volume is "The Intellectual Revolution: Selections from Euripides, Thucydides and Plato".

    Intermediate-level Latin texts:

    The reader Alessandro used in his second-year course was the "Oxford Latin Reader", edited by Maurice Balme and James Morwood. However, Alessandro prefers "Wheelock's Latin Reader: Selections from Latin Literature", edited by Richard A. LaFleur.

    Carmina Burana is a collection of poems that is fairly easy and very fun to read.

    An anthology of medieval Latin texts that Alessandro greatly enjoys is "Reading Medieval Latin" by Keith Sidwell. Many of these selections are of intermediate difficulty (a few are very hard).

    The prose works of Seneca bridge the gap between intermediate and advanced.

    Dictionaries and grammars:

    Alessandro's favourite Latin dictionary: The "Oxford Latin Dictionary"

    For medieval Latin: "Dictionary of Medieval Latin from British Sources"

    * the DMLBS is freely searchable at https://logeion.uchicago.edu

    For advanced Latin grammar: "A New Latin Syntax" by E.C. Woodcock

    Alessandro's favourite Greek dictionary: The "Cambridge Greek Lexicon"

    "The Greek Particles" by John Dewar Denniston is the book that's very helpful for reading Plato.

  • 14 - The 2024 Eclipse
    Apr 25 2024

    In this episode, I give you updates from my trip with friends to see the 2024 total solar eclipse. Questions answered include:

    - Why are we bothering to go see it?

    - How many of us will fail to make it to the eclipse?

    - Does it actually get darker during a total solar eclipse, or is that just an optical illusion?

    - What moral dilemma will we face, and what will we do?

    - Whose lav mic will mysteriously fail to work during their interview?

  • 13 - Aaron Silverbook on anti-cavity bacteria
    Nov 20 2023

    In this episode, I speak with Aaron Silverbook about the bacteria that cause cavities, and how different bacteria can prevent them: specifically, a type of bacterium that you can buy at luminaprobiotic.com. This podcast episode has not been approved by the FDA. Specific topics we talk about include:

    • How do bacteria cause cavities?
    • How can you create an anti-cavity bacterium?
    • What's going on with the competitive landscape of mouth bacteria?
    • How dangerous is it to colonize your mouth with a novel bacterium?
    • Why hasn't this product been available for 20 years already?

    Lumina Probiotic (the brand name of this new type of bacterium): luminaprobiotic.com

    Lantern Bioworks (the company making the bacterium): lanternbioworks.com

  • 12 - Holly Elmore on AI pause
    Sep 12 2023

    In this episode, I talk to Holly Elmore about her advocacy around AI Pause - encouraging governments to pause the development of more and more powerful AI. Topics we discuss include:

    • Why advocate specifically for AI pause?
    • What costs of AI pause would be worth it?
    • What might AI pause look like?
    • What are the realistic downsides of AI pause?
    • How the Effective Altruism community relates to AI labs.
    • The shift in the alignment community from proving things about alignment to messing around with ML models.

  • 11 - Divia Eden and Ronny Fernandez on the orthogonality thesis
    Apr 28 2023

    In this episode, Divia Eden and Ronny Fernandez talk about the (strong) orthogonality thesis - that arbitrarily smart intelligences can be paired with arbitrary goals, without additional complication beyond that of specifying the goal - with light prompting from me. Topics they touch on include:

    • Why aren't bees brilliant scientists?
    • Can you efficiently make an AGI out of one part that predicts the future conditioned on some plans, and another that evaluates whether plans are good?
    • If minds are made of smaller sub-agents with more primitive beliefs and desires, does that shape their terminal goals?
      • Also, how would that even work?
    • Which is cooler: rockets, or butterflies?
    • What processes would make AIs terminally value integrity?
    • Why do beavers build dams?
    • Would these questions be easier to answer if we made octopuses really smart?
