#78 – Jacob Trefethen on Global Health R&D

Episode 78

Sunday, September 8, 2024 • Duration 02:30:16

Jacob Trefethen oversees Open Philanthropy’s science and science policy programs. He was a Henry Fellow at Harvard University, and has a B.A. from the University of Cambridge.

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

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?

#77 – Elizabeth Seger on Open Sourcing AI

Episode 77

Thursday, July 25, 2024 • Duration 01:20:49

Elizabeth Seger is the Director of Technology Policy at Demos, a cross-party UK think tank with a program on trustworthy AI.

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.

#67 – Guive Assadi on Whether Humanity Will Choose Its Future

Episode 67

Tuesday, July 18, 2023 • Duration 02:00:07

Guive Assadi is a Research Scholar at the Center for the Governance of AI. Guive’s research focuses on the conceptual clarification of, and prioritisation among, potential risks posed by emerging technologies. He holds a master’s in history from Cambridge University, and a bachelor’s from UC Berkeley.

In this episode, we discuss Guive's paper, Will Humanity Choose Its Future?.

What is an 'evolutionary future', and would it count as an existential catastrophe?
How did the agricultural revolution deliver a world which few people would have chosen?
What does it mean to say that we are living in the dreamtime? Will it last?
What competitive pressures in the future could drive the world to undesired outcomes?
- Digital minds
- Space settlement
What measures could prevent an evolutionary future, and allow humanity to more deliberately choose its future?
- World government
- Strong global coordination
- Defensive advantage
Should this all make us more or less hopeful about humanity's future?
Ideas for further research

#66 – Michael Cohen on Input Tampering in Advanced RL Agents

Episode 66

Sunday, June 25, 2023 • Duration 02:32:00

Michael Cohen is is a DPhil student at the University of Oxford with Mike Osborne. He will be starting a postdoc with Professor Stuart Russell at UC Berkeley, with the Center for Human-Compatible AI. His research considers the expected behaviour of generally intelligent artificial agents, with a view to designing agents that we can expect to behave safely.

You can see more links and a full transcript at www.hearthisidea.com/episodes/cohen.

We discuss:

What is reinforcement learning, and how is it different from supervised and unsupervised learning?
Michael's recently co-authored paper titled 'Advanced artificial agents intervene in the provision of reward'
Why might it be hard to convey what we really want to RL learners — even when we know exactly what we want?
Why might advanced RL systems might tamper with their sources of input, and why could this be very bad?
What assumptions need to hold for this "input tampering" outcome?
Is reward really the optimisation target? Do models "get reward"?
What's wrong with the analogy between RL systems and evolution?

#65 – Katja Grace on Slowing Down AI and Whether the X-Risk Case Holds Up

Episode 65

Saturday, June 10, 2023 • Duration 01:43:43

Katja Grace is a researcher and writer. She runs AI Impacts, a research project trying to incrementally answer decision-relevant questions about the future of artificial intelligence (AI). Katja blogs primarily at worldspiritsockpuppet, and indirectly at Meteuphoric, Worldly Positions, LessWrong and the EA Forum.

We discuss:

What is AI Impacts working on?
Counterarguments to the basic AI x-risk case
Reasons to doubt that superhuman AI systems will be strongly goal-directed
Reasons to doubt that if goal-directed superhuman AI systems are built, their goals will be bad by human lights
Aren't deep learning systems fairly good at understanding our 'true' intentions?
Reasons to doubt that (misaligned) superhuman AI would overpower humanity
The case for slowing down AI
Is AI really an arms race?
Are there examples from history of valuable technologies being limited or slowed down?
What does Katja think about the recent open letter on pausing giant AI experiments?
Why read George Saunders?
