  • Ep 270: The Gradient Descent into Doom. 23.09.2026 1ชม. 43นาที
    A spontaneous set of comments on the ongoing AI scare of 2026. What's happening in the media right now, on social media, in culture and at the highest levels of government. Why the pessimism and catastrophism? What can be done? Quite a few slides are referred to, but I do read through them. Incase you want the video - it's here: https://youtu.be/mItTFoYSCcA
  • Ep 269: The Quantum Observer Effect? 23.09.2026 15นาที
    Youtuber Warren Smith of https://www.youtube.com/@SecretScholars made some remarks about the double slit experiment. I assess his claims.
  • Ep 268: AGI has arrived podcast 08.09.2026 34นาที
    Today CEO of the world's most valuable company, Nvidia, Jensen Huang, announced "AGI has arrived". https://x.com/JensenHuang/status/2096700264569090384?s=20 Some reflections on all that.
  • Ep 267: The Orthogonality Thesis is Moral Relativism. (Response to Sam Harris on AI). 26.08.2026 27นาที
    This is in response to episode 489 of Sam Harris' "Making Sense" podcast - in a section only available via subscription. I have clipped the approximately 60 seconds worth of material I am narrowly responding to for fair use in this commentary. The case unpacked is, roughly, that morality can be disconnected from (is orthogonal to) reason broadly is no more than a restatement of moral relativism - and hence false. Morality and science are about objective reality so cannot be “orthogonal”. Moral progress goes hand-in-hand with reason broadly and any “sufficiently advanced” intelligent system would not only realise this, they must understand it to make unbounded, rapid progress.
  • Ep 266: Facts, Fantasy and Critical Thinking 20.08.2026 32นาที
    A analysis in Popperian style of Candace Owens' "mode" of debate and discussion, approach to evidence and thinking and a comparison to the more mainstream evaluations of this debate.
  • Ep 265: David Deutsch's "The Fabric of Reality" Chapter 14 "The Ends of the Universe" Part 2 The Omega Point 15.08.2026 1ชม. 28นาที
    All about the distant future. What does cosmology tell us about the fate of the universe, life and intelligence in some ultimate sense? Frank Tipler's The Omega Point Theory is the primary focus, but throughout we consider the centrality of The Turing Principle for predictions about the future of the cosmos, Roger Penrose's "Conformal Cyclic Cosmology" and some of Freeman Dyson's ideas. Timestamps and Chapters: 0:00 – Introduction: Longevity, Immortality, the Singularity & the Omega Point 5:50 – Recap: The Four Strands, Knowledge & the Multiverse 8:20 – Frank Tipler’s Omega Point Theory Introduced 9:00 – Anthropic Principles (Weak, Strong & Final) 10:30 – The Turing Principle as the Key to the Omega Point 1 3:40 – Modern Cosmology Challenges: Expanding Universe, Dark Energy & Heat Death 20:20 – Cosmological Models That Allow Unlimited Computation (Big Crunch Conditions) 22:00 – Tipler’s Rejoinders & the Case for Eventual Collapse 24:00 – Computers Near the Omega Point & Mutual Implication with the Turing Principle 30:00 – Defending the Strong Turing Principle & the Comprehensibility of Reality 35:00 – Infinite Thoughts, Virtual Reality & Colonisation Deadlines 37:00 – Roger Penrose’s Conformal Cyclic Cosmology (CCC) 43:00 – Freeman Dyson’s Ideas & Infinite Computation in an Expanding Universe 46:50 – Properties of the Omega Point: Omniscience, Omnipotence & Omnipresence 1:15:00 – The Omega Point as “God”, Resurrection & Virtual-Reality Heaven 1:18:50 – Critique of the Technological Singularity (Kurzweil) & Mind Uploading 1:22:00 – The Limits of Far-Future Prediction (Ancient Builder Analogy) 1:25:00 – Conclusions & Takeaways: Take the Turing Principle Seriously
  • Ep 264: David Deutsch's "The Fabric of Reality" Chapter 14 "The Ends of the Universe" Part 1 31.07.2026 44นาที
    What do our best explanations tell us about the ultimate ends of the universe? What is the difference between forming a world view about any one of the four strands (evolution, epistemology, quantum physics or computation) versus taking all four of them seriously?
  • Ep 263: David Deutsch's "The Fabric of Reality" Chapter 13 "The Four Strands" Part 4 - and final. 05.07.2026 1ชม. 30นาที
    How do the Four Strands of the Fabric of Reality - Quantum Physics, Computation, Epistemology and Evolution by Natural Selection hold together? What does taking them each seriously and all of them together seriously? Is it possible to construct a worldview without one of them or based on a single one alone? What do they imply about free will and consciousness? Doesn't making progress require us to assume them false? All this and more.
  • Ep 262: David Deutsch's "The Fabric of Reality" Chapter 13 "The Four Strands" Part 3 04.05.2026 1ชม. 3นาที
    This episode is heavily focussed on Dawkin's "Selfish Gene" explanation of Darwin's evolution by natural selection. Obviously there are readings from the relevant part of this chapter from The Fabric of Reality but I augment that with sections from "The Selfish Gene" itself as well as "The Beginning of Infinity" as well as a larger portion of me providing additional unpacking and exposition.
  • Ep 261: Objective Morality II 24.04.2026 38นาที
    Do not destroy the means of error correction. A deep unification of knowledge akin to unifying quantum theory with computation to create the theory of quantum computation. David Deutsch will be known for not merely forging the basis of quantum computing but also a new basis for morality and epistemology. I explain much of that here. "What should we do next?" is a question with an answer that is right or wrong, good or evil, better or worse. All existing moral frameworks philosophers debate are theories that can serve as criticisms of "what to do next". Morality is as objective as domain as mathematics, physics or anything else. Relativism, like it's sister philosophy dogmatism is false.
  • Ep 260: I don't believe it! 05.04.2026 1ชม. 6นาที
    Response to a question about my discussion with  @drpeterboghossian  here: https://youtu.be/72vhtT0pFmA?si=hAx1kPho4DkLkBFN This is yet another way of coming at a critique around the concept of "belief" or those who profess to "believe" and so on using Deutsch's approach that knowledge is "information with causal power". I explore that for around the first 40 mins. If you're in a hurry, skip to the final 15 or 20 minutes where I get to responding to the meat of the matter in the question itself.
  • Ep 259: Reaction to Michael Levin Part 3: Bait and Switch, Podcastistan and Surprising(?) algorithms. 11.03.2026 59นาที
    In this, the third and final part of a series, I break down some work Michael Levin has done with sorting algorithms. That seems very dry until you hear his claim that these algorithms that are well known and have been studied for decades exhibit extremely unusual behaviour never before spotted because "no one ever bothered to look". This part of the interview is between Ferris and Levin is referring to this paper: https://journals.sagepub.com/doi/10.1177/10597123241269740 which is available on the arXiv at https://arxiv.org/pdf/2401.05375 and which a Forbes writer authored this "explainer" of sorts here: https://www.forbes.com/sites/andreamorris/2025/11/13/the-secret-life-of-algorithms/ and which Levin himself explains here: https://thoughtforms.life/algorithms-redux-finding-unexpected-properties-in-truly-minimal-systems/ Michael Levin has done some very interesting work in biology around worms regrowing heads and so on. But this "research" is quite a departure from that. Get my book here: https://www.amazon.com/Farthest-Reaches-Important-Entities-Universe/dp/B0GRR2LLZV/ref=sr_1_1?crid=157SNHQC0QFHK&dib=eyJ2IjoiMSJ9.D5jlSZxhaQmrjzrnV209t0-bvV-i5un48Fwu5tb8Y42AKywnL9YRXJ8ylEe8EPH2SBLoKpU2AXag0llMQ3XfVILgUrAiohRqKjRaBiNdrcUqVQIV6MyEUBdAWiwjufzS4dCs_m5HBm-Px8errzQVyqzjO7F9UEGMeOgpjDGyJBB5Qbi98LHHSYb91z0J5sP9fRT8BaP4wXNvi4p0Va4kbQNBXxPjUb0OOwORDDGbWGo.HBT8A2pQNHYK8NyTIn91VtLaPJEMt17xp7qCt4bNcv4&dib_tag=se&keywords=the+farthest+reaches&qid=1773231582&sprefix=the+farthest+reac%2Caps%2C346&sr=8-1
  • Ep 258: Reaction to Michael Levin, Part 2: Bioelectricity, Consciousness and Knowing 16.02.2026 1ชม. 38นาที
    This is the second in a multipart series where I react to some interviews with ‪@drmichaellevin‬ a biologist who, among other things, specialises in bioelectricity. His research can be found here: https://www.drmichaellevin.org and his "explainer articles" for his own professional papers here: https://thoughtforms.life . In this episode I mention the discussion he had with ‪@timferriss‬ which is found here:    • Dr. Michael Levin — Reprogramming Bioelect...   Part 1 is here:    • Reaction to Michael Levin, Part 1: Categor...   Part 3 will be out soon.  
  • Ep 257: Reaction to Michael Levin, Part 1: Categories and Continuums. 10.02.2026 1ชม. 8นาที
    This is the first in a multipart series where I react to some interviews with  @drmichaellevin  - a biologist who, among other things, specialises in bioelectricity. His research can be found here: https://www.drmichaellevin.org/publications/ and his "explainer articles" for his own professional papers here: https://thoughtforms.life . Although in this first episode I mention the discussion he had with  @timferriss  which is found here: https://youtu.be/kz1jnoKfRrI?si=O-TTxrVleMbDsEH8 I never actually get to it in this first part. I do comment on Michael's interview with  @lexfridman  found here: https://youtu.be/Qp0rCU49lMs?si=jYN_SbXCd6ziO_pe and even then only in brief because I'm verbose. Part 2 will be out soon.
  • Ep 256: David Deutsch’s ”The Fabric of Reality” Chapter 13 ”The Four Strands” Part 2 30.01.2026 1ชม. 9นาที
    Comparing Kuhn and Popper on Quantum Theory: Here we go deeper into the differences between Karl Popper and Thomas Kuhn's account of how science moves from one theory to another. David applies the theory set out in part 1 of this chapter to the specific case of quantum theory. Did social forces have a major impact on whether quantum theory was adopted as Kuhn would have it, or were rational factors like argument and experiment crucial in dictating how science broadly, physics and the community of physicists took on a new "counter-cultural" idea?
  • Ep 255: Does this research explain how LLMs work? 15.01.2026 1ชม. 22นาที
    I take a look at these three papers: 1. https://www.arxiv.org/abs/2512.22471 2. https://arxiv.org/abs/2512.23752 3. https://arxiv.org/abs/2512.22473 Collectively titled "The Bayesian Attention Trilogy" along with some other material - in particular an interview with one of the authors "Vishal Misra" - https://www.engineering.columbia.edu/faculty-staff/directory/vishal-misra For those familiar with my output on this you can probably skip to about halfway through at 42:40. Prior to this is a lot of background on Induction, Bayesianism, Critical Rationalism and so on that people may have heard from me before in different contexts - although for what it's worth these are new ways of expressing those ideas. At the end I am reacting to a video found here: https://www.youtube.com/watch?v=uRuY0ozEm3Q
  • Ep 254: Australia: The Land of Bans. (Social Media prohibited for under-16s. Analysis of the arguments "for".) 25.12.2025 1ชม. 33นาที
    This 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.
  • Ep 253: Further Comments on the Bondi Massacre. 22.12.2025 35นาที
    Here I remark on comments made by Australian Home Affairs Minister Tony Burke and Education Minister Jason Clare and then make some broader points about the recent tragedy on Bondi Beach. This is part 2 of a response to the Prime Minister of Australia and others.
  • Ep 252: Response to the Prime Minister of Australia 19.12.2025 1ชม. 5นาที
    A reaction "episode" where I make some remarks about a speech by Anthony Albanese, Prime Minister of Australia, in the wake of the Bondi Beach Massacre by Islamists terrorists who attacked Jews at a Hanukkah celebration on 14 December, 2025
  • Ep 251: OK Doomer! 11.12.2025 31นาที
    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.
