Ep 254: Australia: The Land of Bans. (Social Media prohibited for under-16s. Analysis of the arguments "for".)
Dec 2501:33:08Tap to summarizeThis is effectively part 3 in a series of responses to the Prime Minister of Australia about censorship, legislation, policy, philosophy, Bondi and Social Media. The Prime Minister attempted to explain, as best he could, the reasons for banning under-16 year olds from certain social media platforms. I remark on an interview he conducted and make some broader remarks in conclusion to a short series on his response to the Bondi tragedy and other issues. These are largely off-the-cuff rather than prepared remarks - so expect the tone, tenor, tempo and expression to be a little different than usual.

Dec 1100:31:08Tap to summarizeThis is a reproduction of a talk I gave to some trainee surgeons in Sydney who, among other things, were learning about AI as it was affecting their own field. It is, in a sense, a summary of many of the points I have been making recently on this channel with respect to AI and pessimism around it.
Transcribe →Ep 250: The Farthest Reaches - Audiobook
Nov 1204:19:29Tap to summarizeThe Farthest Reaches is a book about "Explanatory Universality". Explanatory Universality is a concept introduced by physicist and philosopher David Deutsch in his book "The Beginning of Infinity". Links, as mentioned in the audiobook can be found in the ebook available for free here: https://www.bretthall.org/the-farthest-reaches.html This present work follows the logic of that concept as it applies to education, psychology, morality, immigration, the trans issue, "evolutionary psychology" and the significance of people to physical reality and much more. This version is significantly longer and with superior audio production compared with the original podcast of the same name. These are the chapters and timestamps: 00:00 Preface 21:51 Chapter 1 - Universality and Reach 29:38 Chapter 2 - The Reach of Explanatory Universality 38:53 Chapter 3 - Explaining Explanatory Universality 47:31 Chapter 4 - Explanatory Universality and Education 1:00:27 Chapter 5 - Explanatory Universality, Psychological Science and IQ 1:03:41 Chapter 6 - Explanatory Universality and Adopting Culture 1:10:26 Chapter 7 - Explanatory Universality and IQ Part 2 1:14:58 Chapter 8 - Explanatory Universality and the “Trans Issue” 1:22:57 Chapter 9 - Explanatory Universality and Immigration 1:48:12 Chapter 10 - Explanatory Universality and Ethnicity 2:11:39 Chapter 11 - Explanatory Universality and Multiculturalism 2:23:22 Chapter 12 - Explanatory Universality and Mental Illness 2:32:35 Chapter 13 - Explanatory Universality, Hangups and Sexuality 2:41:26 Chapter 14 - Explanatory Universality and The Woke Left and The Woke Right 2:48:29 Chapter 15 - Explanatory Universality and Optimism 2:58:20 Chapter 16 - Explanatory Universality and Artificial Intelligences 3:09:59 Chapter 17 - Universality, Freedom of Speech and Freedom of Reach 3:17:07 Chapter 18 - Explanatory Universality and Evolutionary Psychology 3:31:20 Chapter 19 - Explanatory Universality and Individuality 3:39:05 Chapter 20 - Summary and Conclusions 4:08:18 Acknowledgements and Afterward The author thanks David Deutsch ( @DavidDeutschPhysicist ) Naval Ravikant ( @NavalR ) Reid Nicewonder ( @CordialCuriosity ) and Peter Boghossian ( @drpeterboghossian ) for their crucial support and engagement.

Transcribe →Ep 248: AI and Philosophy of Science
Oct 1301:25:39Tap to summarizeThis is the extended "director's cut" of a talk delivered for "RatFest 2025" (next year to be "Conjecture Con"). This also serves as a supplement to my "Doom Debates" interview which can be found here: https://youtu.be/koubXR0YL4A?si=483M6SPOKwbQYmzb It is simply assumed some version of "Bayesian reasoning" is how AI will "create" knowledge. This misconception permeates the https://ai-2027.com paper, as well as Bostrom and Yudkowsky's work on this, as well as that of every other AI "Doomer" and even on the other extreme the so-called "AI-Accelerationists". All of that indicates a deep misconception about how new explanations are generated which comes from a deep misconception about how science works because almost no one in the field of AI seems to think the *philosophy of* science is even relevant. I explain what has gone wrong: 00:00 Introduction 09:14 The Big Questions and the new Priesthoods 18:40 Nick Bostrom and Superintelligence 25:10 If anyone builds it, everyone dies and Yudkowsky. 33:32 Prophecy, Inevitability, Induction and Bayesianism. 41:42 Popper, Kuhn, Feyerabend and Lakatos. 49:40 AI researchers ignore The Philosophy of Science. 58:46 A new test for AGI from Sam Altman and David Deutsch? 1:03:35 Accelerationists, Doomers and “Everyone dies”. 1:10:21 Conclusions 1:15:35 Audience Questions

Sep 1200:44:43Tap to summarizeChapters 1 to 4 of a multi-chapter series about the reach of what I argue is one of the most important lessons to learn in order to solve many pressing problems: explanatory universality. This podcast provides an explanation that "explanatory universality" is an idea of such depth it may have among the greatest reach of any idea.
