About this Episode
Vaden manages to penetrate deep into the rationalist stronghold in San Francisco, the Mecca of Yudkowsky himself, and - exactly as we'd all expect - gets into an epistemological standoff. Can he shake a Bayesian's credence in Bayesianism, or does he find in himself a Jaynesian acolyte, ready to make sure that no Dutchman is going to be able to mess with his books?
We discuss
- Critical rationalism vs. Bayesianism
- Toby Ord's doom estimates
- Asteroids vs. AI risk
- What probabilities measure
- Comparing made-up numbers
- Is probability a law?
- Cox's theorem and Dutch books
- COVID models and Monte Carlo
- AI expert surveys
- How we actually decide
- Bentham's Bulldog and Pascal's mugging
- Animal consciousness and vegetarianism
- Strong longtermism
