This 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.

The 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.

This 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

Chapters 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. Chapters: 00:12 Chapter 1 - Universality and Reach 09:09 Chapter 2 - The Reach of Explanatory Universality 20:01 Chapter 3 - Explaining Explanatory Universality 30:23 Chapter 4 - Explanatory Universality and Education

We are told by people working in the field, researchers and those who publish academic papers on the topic that artificial intelligence or deep learning or LLMs or Machine Learning or Recurrent Neural Networks - call them what you like - employ some form of inductive reasoning. But do they? What is inductive reasoning? What is deductive or adductive for that matter? Is "new physics" or other new science being discovered by the most recent and best chatbots or other "artificially intelligent" computer systems? My response to all that is contained herein.

Woke is a rejection of the truth, the good, the beautiful. Is the best response a return to traditional religion? Are some dogmas worth defending?

This is a "megasode" combining two episodes from Youtube all about the Simulation Hypothesis. In the first part I provide the philosophical basis for the simulation hypothesis as explained especially by Nick Bostrom and compare it to other "ultimate" explanations of reality. In part 2 I discuss and evaluate the arguments made by Scott Adams and Joe Rogan who endorse some version of Bostrom's argument.

I recently had the opportunity to participate in "Spectrum Street Epistemology" with @drpeterboghossian and a number of others including @destiny . This episode was inspired by both that event and the many other conversations I had with Peter, Reid, David, Evan, Mia and Travis across the days I spent in Florida with those excellent people engaged in the important work of defending the Enlightenment. This is a sort of disjointed episode as I have in mind a particular audience of sophisticated thinkers on epistemology so I meander through my own worldview, take a historic look at why it is "belief" and "degrees of belief" or "strength of feeling", "confidence" and so on arose and became an important improvement on more primitive ways of thinking about the world. I compare all of that to what I argue is the most rational way of conceiving of "critical thinking". I end with some personal reflections. If you go to Peter's channel I imagine the many conversations we recorded together will be gradually released in the coming days and weeks. Compared to what I do here: their's is a very professional production! The videos accompanying the audio are a mixture of my own poorly shot camera work and stock footage - just so the viewer does not have to stare at nothing but my head for ~40 minutes. 00:00 Introductions 01:00 Are humans unique…just like every other species? 03:45 We are 98% the same as chimpanzees? 07:00 Was there an “Adam” - a first person? 09:00 The first creative minds 10:10 The evolution of authoritarianism 12:30 Medieval societies vs primitive tribalism 13:20 Early individualism, empiricism, rationalism and reason 16:10 Empiricism, rationalism and inductivism as “appeals to authority” 18:25 Belief and the weight of evidence 21:00 “Updating one’s priors”. 22:20 The God of the Subjectivism 23:30 Fossils 26:04 Better ways of thinking 29:00 Knowing and believing 31:00 Moving beyond “degrees of belief” and subjectivism 32:00 Knowledge: what it is 34:00 Knowing is binary 36:00 Reason is more than feeling 36:55 Reflecting on Spectrum Street Epistemology 41:05 Gratitude and acknowledgements

The first part of my discussion of the differing visions of science and how scientific knowledge "grows" (or not) according to Thomas Kuhn vs Karl Popper as outlined in this chapter of "The Beginning of Infinity". Kuhn's "The Structure of Scientific Revolutions" explains the concept of a "paradigm" and "paradigm shifts" comparing "revolutionary" and "normal" periods of science. Kuhn's work remains the most cited in the social sciences and so far more people - especially in academia - are familiar with his work that Popper's. What explains this? What does Kuhn have to say? And what does a "critical rationalist" perspective on the growth of knowledge have to say in response to Kuhn?

I take another deep dive into a deeply insightful and original lecture by Karl Popper: The Myth of the Framework. In this first part (of 4) I spend most of the episode unpacking our motivations, Popper's own thoughts on his success in combating bad ideologies and the purposes of discussion. Indeed this piece can be considered an instruction manual for discussions: how to have them and why. Below: timestamps for this episode: 00:00 Purpose of this new series 05:41 Woke, DEI and Popper 10:47 Popper in his own words on his “success” 12:23: Marxism and Relativism as “ideas that survive” 19:47 Popper in the modern day 22:30 Frameworks and “echo chambers”. 26:05 Some personal anecdotes and reflections 32:43: Defending an idea is different to explaining one. 35:00 Personal anecdotes. 47:47 Discussions 49:33 Why do we talk to each other? :) 59:13 The Myth of the Framework.

The best part! If you missed the others, don't miss this one. All four strands come together to explain the possibility of time travel and the intrigue that arises when considering travelling to "your" past or future to visit "yourself". Rough timestamps follow: 00:00 introduction and the significance of virtual reality 04:03 Physically possible renderings and resolving paradoxes 07:30 what does VR time travel tell us about physics? 11:05 Personhood and time travel 13:30 Highly unlikely events, the multiverse and “never”. 15:45 General Relativity and time travel 18:51 David’s 70th birthday online acknowledgement https://dd70th.weebly.com/ 20:14 Past directed time travel: the consensus 25:25 Black holes, wormholes and time travel 34:10 More on paradoxes and quantum gravity 38:00 The unpredictability of the growth of knowledge . 42:05 Visitors from the future 45:50 Time travel, BoI and Fungibility 56:00 Knowledge Paradoxes? 1:00:40 Creation ex nihilo and “recombination”. 1:06:39 Biological and explanatory knowledge 1:11:32 Useless information and the resolution of knowledge “paradoxes” 1:15:23 The knowledge “crystal” - structure across the multiverse. 1:22:18 The entire biosphere as a computation. 1:26:20 Civilisations as virtual reality renderings. 1:30:00 The four main strands and time travel.

An outside broadcast as you will hear. Image generation and virtual reality provide a window on the physics of time travel. Why is that? And what about all those time travel paradoxes? The resolution to all is found herein.
