Liron Shapira, host of [Doom Debates], invited us on to discuss Popperian versus Bayesian epistemology and whether we're worried about AI doom. As one might expect knowing us, we only got about halfway through the first subject, so get yourselves ready (presumably with many drinks) for part II in a few weeks! The era of Ben and Vaden's rowdy youtube debates has begun. Vaden is jubilant, Ben is uncomfortable, and the world has never been more annoyed by Popperians.

Follow Liron on twitter (@liron) and check out the Doom Debates youtube channel and podcast.

We discuss

Whether we're concerned about AI doom
Bayesian reasoning versus Popperian reasoning
Whether it makes sense to put numbers on all your beliefs
Solomonoff induction
Objective vs subjective Bayesianism
Prediction markets and superforecasting
