ToKCast

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:

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.

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?

A summary of some arguments made in the previous 4 parts, and a conclusion to my evaluation of https://ai-2027.com I refer to Daniel Kokotajlo's paper which contained an earlier set of predictions made in 2021 about the 5 years leading to 2026 which is found here https://www.lesswrong.com/posts/6Xgy6CAf2jqHhynHL/what-2026-looks-like Note that Part 4 is here: https://youtu.be/C3jDjuSLBv0 Part 3 is here: https://youtu.be/7P-UlHiTins Part 2 is here: https://youtu.be/o3Rdj37UJjw Part 1 is here: https://www.youtube.com/watch?v=Uq_txKy-XMQ Credit to  ⁨@drpeterboghossian⁩  for the inspiration,  ⁨@NavalR⁩  for the support and  ⁨@DavidDeutschPhysicist⁩  for many of the arguments made with errors, as always, my own.

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.

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?

The second in the series on "The Myth of the Framework" paper.
