We discuss:

• How to begin thinking about quantifying animal experiences in a cross-comparable way
• Whether the ability to feel pain is unique to big brained animals, or more widespread in the tree of life
• How fish farming compares to poultry and livestock farming
• How worried to be about bird flu zoonosis
• Whether different animal species experience time differently
• Whether positive experiences like joy could make life worth living for some farmed animals
• How animal welfare advocates can learn from anti-corruption nonprofits

Dan Williams is a Lecturer in Philosophy at the University of Sussex and an Associate Fellow at the Leverhulme Centre for the Future of Intelligence (CFI) at the University of Cambridge.

You can find links and a transcript at www.hearthisidea.com/episodes/williams.

We discuss:

• If reasoning is so useful, why are we so bad at it?
• Do some bad ideas really work like ‘mind viruses’? Is the ‘luxury beliefs’ concept useful?
• What's up with the idea of a ‘marketplace for ideas’? Are people shopping for new beliefs, or to rationalise their existing attitudes?
• How dangerous is misinformation, really? Can we ‘vaccinate’ or ‘inoculate’ against it?
• Will AI help us form more accurate beliefs, or will it persuade more people of unhinged ideas?
• Does fact-checking work?
• Under transformative AI, should we worry more about the suppression or the proliferation of counter-establishment ideas?

In this episode we talked about open source the risks and benefits of open source AI models. We talk about:

• The argument for explosive growth from ‘increasing returns to scale’
• Does AI need to be able to automate R&D to cause rapid growth?
• Which theories of growth best explain the Industrial Revolution; and what do they predict from AI?
• What happens to human incomes under near-total job automation?
• Are regulations likely to slow down frontier AI progress enough to prevent this? Might AI go the way of nuclear power?
• Will AI hit on resource or power limits before explosive growth? Won't it run out of data first?
• Why aren't academic economists more interested in the prospect of explosive growth, if indeed it is so plausible?

In this episode we talked about open source the risks and benefits of open source AI models. We talk about:

• Life-saving health technologies which probably won't exist in 5 years (without a concerted effort) — like a widely available TB vaccine, and bugs which stop malaria spreading
• How R&D for neglected diseases works —
• How much does the world spend on it?
• How do drugs for neglected diseases go from design to distribution?
• No-brainer policy ideas for speeding up global health R&D
• Comparing health R&D to public health interventions (like bed nets)
• Comparing the social returns to frontier (‘Progress Studies’) to global health R&D
• Why is there no GiveWell-equivalent for global health R&D?
• Won't AI do all the R&D for us soon?

You can find links and a transcript at www.hearthisidea.com/episodes/seger In this episode we talked about open source the risks and benefits of open source AI models. We talk about:

• What ‘open source’ really means
• What is (and isn’t) open about ‘open source’ AI models
• How open source weights and code are useful for AI safety research
• How and when the costs of open sourcing frontier model weights might outweigh the benefits
• Analogies to ‘open sourcing nuclear designs’ and the open science movement

Note that this episode was recorded before the release of Meta’s Llama 3.1 family of models. Note also that in the episode Elizabeth referenced an older version of the definition maintained by OSI (roughly version 0.0.3). The current OSI definition (0.0.8) now does a much better job of delineating between different model components.
