We engage in fascinating discussions with pre-eminent figures in the AI field. Our flagship show covers current affairs in AI, cognitive science, neuroscience and philosophy of mind with in-depth analysis. Our approach is unrivalled in terms of scope and rigour – we believe in intellectual diversity in AI, and we touch on all of the main ideas in the field with the hype surgically removed. MLST is run by Tim Scarfe, Ph.D (https://www.linkedin.com/in/ecsquizor/) and features regular appearances from MIT Doctor of Philosophy Keith Duggar (https://www.linkedin.com/in/dr-keith-duggar/).","last_synced_at":null,"page_url":"https://stenobird.com/podcast/machine-learning-street-talk"},"episode":{"title":"The Universal Hierarchy of Life - Prof. Chris Kempes [SFI]","slug":"the-universal-hierarchy-of-life-prof-chris-kempes-sfi","published_at":"2025-10-25T10:52:43+00:00","page_url":"https://stenobird.com/podcast/machine-learning-street-talk/the-universal-hierarchy-of-life-prof-chris-kempes-sfi","show_page_url":"https://stenobird.com/podcast/machine-learning-street-talk","url":"https://podcasters.spotify.com/pod/show/machinelearningstreettalk/episodes/The-Universal-Hierarchy-of-Life---Prof--Chris-Kempes-SFI-e3a17m6","audio_url":"https://traffic.megaphone.fm/APO3213100229.mp3","summary":"Life is not defined by Earth-based biochemistry, but by universal principles of physics and information.
