  • AI SAFETY - A SCEPTICAL VIEW - Stephen Wolfram PhD #76
    What are the benefits and risks of developing advanced AI? What kind of safety precautions could we take? Could we risk never making future discoveries, by over-limiting today’s AI in pre-emptive safety regulations?In this episode we get a sceptical evaluation of the complex debate that’s currently raging on artificial Intelligence safety, aiming to get a balanced view of the extremely useful applications versus the currently hugely publicised existential risks, and evaluate the safety measures and legislative frameworks that are being considered to help avoid risk to humans. To do this we trace the path from today’s artificial intelligence right up the ever steeper curve towards artificial super intelligence; we risk risk assess the unpredictability of emergent properties of such systems; we assess the future of work, and the potential loss of control of our culture as AI starts to outnumber us and generate more and more of the media we consume.My guest today has a unique take on these issues which took me by surprise, as he disagrees with the alarmism and call for harsh regulation, whilst openly predicting that emergent properties will more or less guarantee safety hazards. The fact that he has been at the cutting edge of computer science for over 40 years, creating computer language and Ai solutions, makes him well placed to provide a counterpoint to the AI safety campaigners calling for collective action. He is of course physicist, computer scientist and tech entrepreneur Stephen Wolfram. In 1987 he left academia at Caltech and Princeton behind and devoted himself to his own computer systems at his company Wolfram Research. He’s published many blog articles about his ideas, and written many influential books including “A new kind of science”, “A project to find the fundamental theory of physics”, and “Computer modelling and simulation of dynamic systems”, and most recently “The Second law” about the mystery of Entropy. What we discussed:00:00 Intro. 06:30 Stephen’s first forays into neural nets in the early 80s.09:30 Cellular Automata.11:00 Can you make the knowledge of the world available via computers?13:00 Wolfram Alpha: A non-AI AI. 17:45 Can AI solve science?22:00 AI is great at rough answers, worse at the detail.33:00 Artificial General intelligence, A.G.I.42:00 The pros & cons of super intelligence.47:40 Chat GBT’s unpredicted peculiarities.54:00 The spread of mistruth. 58:00 AI and the future of work.01:05:20 Businesses leading automation push.01:09:00 AI will outnumber us and network, changing our culture.01:11:00 AI will follow a banal ‘mean’.01:16:30 The AI Safety debate.01:21:00 We have no choice, it will be developed anyway.01:22:00 Ai systems may have feelings, we don’t know.01:25:00 Stephen’s non-interventionist safety approach.References: Stepehn Wolfram, “A project to find the fundamental theory of physics”,Stephen Wolfram, “The Second Law” The History of “Neural Nets” since 1943, (Warren McCulloch and Walter Pitts paper)Stephen Wolfram, “Can AI solve science?” article

  • OUT OF BODY EXPERIENCES: THE ANTHROPOLOGY - Samantha Lee Treasure #75
    What are the contents of Out of Body Experiences? How closely do they map the actual physical world? Is it possible to induce them purposefully? How do modern practices compare to indigenous shamanic ones?In this Episode we look at the scientific, religious, cultural and historical contexts of Out of Body Experiences, also known as astral projection - so the experience in which an individual appears to leave their body and be able to travel around the world and into other dimensions, often meeting other worldly entities, similarly to DMT psychedelic experiences, (see Episode #73, “DMT Entity Experiences”). So, we get into the phenomenology- the various things people experience; potential neurobiological explanations; and the possibility of inducing the experiences on purpose and of exploring alternate realities; we get into indigenous traditions of ‘Shamanic flight’ and which people might be predisposed to these alternate states of consciousness; and we end up talking about a potential connection between OBE, sleep paralysis and ludic dreaming.To discuss this slippery topic, we have a researcher who is also a lifelong experiencer, who has devoted her career to trying to understand these phenomena, the medical anthropologist and author Samantha Lee Treasure; she has an MA in Medical Anthropology from SOAS university in London, has been a brain science research assistant at the University of Liege, and has just released her first book on the topic, “Out of Body experiences”, the release of which this episode is timed to coincide with.What we discuss:00:00 Intro.11:30 What is medical anthropology?16:00 OBE entity research.22:15 Samantha’s New Book - getting beyond preconceptions.25:50 OBE vs Astral projection - bypassing the taboo.30:00 Common reported OBE experiences.33:00 Mental body schemas and projected models of the world.37:00 Do OBE’s map the real world accurately?45:00 Olaf Blanke - the Temporoparietal junction discovery.48:45 No sense of smell during OBE nor processed by the TPJ.49:40 Techniques to induce OBE’s intentionally.53:45 Bob Monroe’s perspective switching technique.55:30 Shamanic flight practices in Tuva, Siberia.59:35 The sonezen - the perceiving mind self.01:01:00 This is not for everyone, it can be scary.01:05:00 The predisposition for some to have these experiences.01:10:45 Crossovers between NHI Contact and OBE entity experiences.01:14:20 Genealogical predispositions.01:18:25 “Reality Shifting” and the role of intention in OBE.References: Samantha Lee Treasure, “Out-of-Body Experiences: Explorations and encounters with the astral plane”.Stephen Le Berge, “Pre-sleep treatment with Galantamine stimulates lucid dreaming” paperOlaf Blanke, “Linking out-of-body experience and self processing to mental own-body imagery at the temporo-parietal junction” paper.

  • INTELLIGENT LIFE ON OTHER PLANETS, WHAT ARE THE CHANCES? - Adam Frank PhD #74
    How do astronomers detect the conditions for life and techno-signatures on exoplanets many lightyears away? What conditions on earth give us clues to how life might have formed elsewhere? How do intelligent civilisations evolve to technomaturity before they destroy themselves?So in this episode we have the mysterious arising of life and eventually intelligent life on our planet to try and explain, to then apply that to our search for other intelligent life in the cosmos. So to explain that we’re going to be getting into the co-evolution of the geosphere and the biosphere on earth and their corresponding feedback loops; the possibility of planetary level intelligence; the difficulty of laying a technosphere on top of the geo and biosphere, and the risk of civilisations wiping themselves out before learning how to harmonise the technosphere with the biosphere; We’ll be looking at the changes in the field of SETI (the Search for Extraterrestrial Terrestrial Intelligence), since we can now identify potentially life sustaining exo-planets in nearer parts of the galaxy; we’re going to get into the newly funded search for techno signatures from advanced civilisations, and potential space junk from the many civilisations that presumably didn’t make it; lastly we’re going to discuss recent claims of ancient and alleged present visitations to earth by extra terrestrial intelligence.Fortunately to face these tough and complex issues, our guest is a world specialist in astrobiology, with a talent for making these topics fun and imaginative, an astrophysics professor at the University of Rochester, Professor Adam Frank. He’s the author of over 200 scientific papers and 6 books for the general public including, “The Blind Spot: why science cannot ignore human experience” and “The Little book of Aliens” which we’ll be focussing on today. He’s also an award winning science communicator, on a mission to raise public awareness about existential risk and science in general.What we discussed:00:00 Intro.05:20 The importance of experience.07:00 The limits between the expressible and the inexpressible.09:10 Semantic Information: life as self organising, autonomous agents.15:00 There’s stuff you can’t talk about - there’s only the silence16:20 The Basian probability of other life in the universe.20:00 The ingredients for life on this earth.22:30 The codependence between Geo and Biosphere.22:60 Gaian feedback loops. 27:00 The earth is not conscious but it is an agent.29:45 Mind is a process, it’s not just in the head.33:25 The fluidity of individuality.34:30 Distributed Cognition - bacteria, fungal networks etc.38:30 A fundamental reimagining of what we mean by ‘Nature’.39:30 There is no disembodied perspective.41:00 Geosphere to Biosphere to technosphere maturity.47:30 The biosphere offers a model for what planetary intelligence looks like.48:00 The history of search for extra terrestrial Intelligence, SETI49:00 The Drake equation - 7 requirements for intelligence life.53:45 We’ve never looked - a tiny amount of the sky has been studied.54:00 Exoplanets: searching for biosgnatures and techno signatures.56:00 Technospheres: Kardeshev scale and Dyson Spheres.59:00 Techno junk from dead civilisations.01:02:30 UFO’s need more data to be taken seriously.01:08:20 UFO’s could be surveilling their spy tech.01:10:00 Pros and Cons of solar system settlement.References:Adam Frank, Evan Thompson, Marcelo Gleiser, “The Blind Spot: Why science cannot ignore human experience”.Adam Frank, “The Little Book of Aliens”Adam Frank, David Grinspoon, Sarah Walker - Intelligence as a planetary scale process.Lynn Margulis - Evolutionary Biologist.David Krakauer et al, An information theory view of individuality Frank Drake - ⁠Project Ozma⁠Jason Wright - SETI meta-analysisExoplantets.orgAdam Frank - New York Times ‘I’m a Physicist Who Searches for Aliens.

  • DMT ENTITY ENCOUNTERS, A QUANTITATIVE STUDY - Dr David W Lawrence #73
    What’s the architecture of a DMT experience, who are the entities that regularly interact and what’s their message? How can DMT therapy facilitate positive mental health outcomes?In this episode we’re going to learn about the bizarre types of experience that users of DMT have; DMT being the most powerful hallucinogenic molecule on the planet. So we’ll be getting into the background of psychedelics for mental health; and the particularities of DMT, the active ingredient in Ahyuasca and the psychedelic that most often presents entities that interact meaningfully with the experiencer; we’re going to discuss the different types of entities: from mythological creatures, to Gods and Demons, to machine elves and aliens, and the significance of these same characters appearing significantly often without an obvious primer; we’ll also discuss the importance of mystical experience and teacher /guide experiences to positive mental health outcomes.Fortunately our guest was the head researcher on a 2022 paper that looked at exactly this topic, the medical doctor and sports scientist professor at the University of Toronto, Dr. David Wyndham Lawrence. He’s published over 35 scientific papers across sports science and psychedelics for medical use.What we discussed:00:00 Intro05:20 Concussion, sports mental health & psychedelic therapy.08:10 Bringing in Robin Carhartt-Harris on the gaps in sports mental health treatment.12:06 Why psychedelics for those already in psychological difficulty?14:04 Serotonin receptor - neuro-protective mitochondria function.15:00 DMT is endogenous to the brain. 18:20 Medical institution meets shamanism.23:50 David’s DMT phenomenology paper.30:10 The architecture of the DMT world.32:60 Mostly positive, interactive entity encounters.37:05 Occasionally negative encounters.38:40 Negative psychedelic experiences study - Jules Evans.40:05 How much “Primers” from pop culture influence experiences.44:00 Alien encounters in %16 of participants.45:30 Medical procedures by entities in 9% of participants.47:05 Mystical experiences in %70 of participants.49:00 Familiarity/ sense of home in the experiences.52:20 Default Mode Network is less active during altered states.48:35 Ego dissolution Vs mystical experience.01:00:00 5meoDMT Vs DMT.01:03:20 Wise teacher experience in 32% of participants.01:05:20 Death bed palliative doses to alleviate fear of death.01:09:50 ‘You’re not ready for this experience’ message.01:11:05 Theories of DMT experiences evaluated.01:12:20 ”All models are false but some are useful”, anonymous statistician.References: David Lawrence, “Phenomenology and content of inhaled DMT” David Wyndham Lawrence and Robin Carhart-Harris, “Sports Medicine, Mental Health & Well-Being, and Psychedelics” Benny Shanon,  “Antipodies of the Mind”Matthew W.
